Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490660, here are decompositions:

23 + 33490637 = 33490660
53 + 33490607 = 33490660
113 + 33490547 = 33490660
131 + 33490529 = 33490660
197 + 33490463 = 33490660
251 + 33490409 = 33490660
263 + 33490397 = 33490660
317 + 33490343 = 33490660

Showing the first eight; more decompositions exist.
