Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627744, here are decompositions:

17 + 31627727 = 31627744
23 + 31627721 = 31627744
167 + 31627577 = 31627744
233 + 31627511 = 31627744
353 + 31627391 = 31627744
593 + 31627151 = 31627744
653 + 31627091 = 31627744
887 + 31626857 = 31627744

Showing the first eight; more decompositions exist.
