Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538704, here are decompositions:

11 + 31538693 = 31538704
227 + 31538477 = 31538704
293 + 31538411 = 31538704
443 + 31538261 = 31538704
563 + 31538141 = 31538704
641 + 31538063 = 31538704
881 + 31537823 = 31538704
983 + 31537721 = 31538704

Showing the first eight; more decompositions exist.
