Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627794, here are decompositions:

31 + 31627763 = 31627794
41 + 31627753 = 31627794
43 + 31627751 = 31627794
67 + 31627727 = 31627794
73 + 31627721 = 31627794
167 + 31627627 = 31627794
193 + 31627601 = 31627794
227 + 31627567 = 31627794

Showing the first eight; more decompositions exist.
