Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627758, here are decompositions:

5 + 31627753 = 31627758
7 + 31627751 = 31627758
31 + 31627727 = 31627758
37 + 31627721 = 31627758
109 + 31627649 = 31627758
131 + 31627627 = 31627758
157 + 31627601 = 31627758
181 + 31627577 = 31627758

Showing the first eight; more decompositions exist.
