Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567904, here are decompositions:

163 + 31567741 = 31567904
211 + 31567693 = 31567904
223 + 31567681 = 31567904
283 + 31567621 = 31567904
607 + 31567297 = 31567904
673 + 31567231 = 31567904
691 + 31567213 = 31567904
751 + 31567153 = 31567904

Showing the first eight; more decompositions exist.
