You can convert it to datetime, and then use DATEADD(DAY, -30, date).
See here.

I suspect many people are finding this question because they want to substract from current date (as is the title of the question, but not what OP intended). The comment of munyul below answers that question more specifically. Since comments are considered ethereal (may be deleted at any given point), I'll repeat it here:
DATEADD(DAY, -30, GETDATE())
TRY THIS:
Cast your VARCHAR value to DATETIME and add -30 for subtraction. Also, In sql-server the format Fri, 14 Nov 2014 23:03:35 GMT was not converted to DATETIME. Try substring for it:
SELECT DATEADD(dd, -30,
CAST(SUBSTRING ('Fri, 14 Nov 2014 23:03:35 GMT', 6, 21)
AS DATETIME))
SELECT DATEADD(day,-30,date) AS before30d
FROM...
But it is strongly recommended to keep date in datetime column, not varchar.
Try this:
SELECT GETDATE(), 'Today'
UNION ALL
SELECT DATEADD(DAY, 10, GETDATE()), '10 Days Later'
UNION ALL
SELECT DATEADD(DAY, –10, GETDATE()), '10 Days Earlier'
UNION ALL
SELECT DATEADD(MONTH, 1, GETDATE()), 'Next Month'
UNION ALL
SELECT DATEADD(MONTH, –1, GETDATE()), 'Previous Month'
UNION ALL
SELECT DATEADD(YEAR, 1, GETDATE()), 'Next Year'
UNION ALL
SELECT DATEADD(YEAR, –1, GETDATE()), 'Previous Year'
Result Set:
———————– —————
2011-05-20 21:11:42.390 Today
2011-05-30 21:11:42.390 10 Days Later
2011-05-10 21:11:42.390 10 Days Earlier
2011-06-20 21:11:42.390 Next Month
2011-04-20 21:11:42.390 Previous Month
2012-05-20 21:11:42.390 Next Year
2010-05-20 21:11:42.390 Previous Year
