Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627202, here are decompositions:

151 + 31627051 = 31627202
223 + 31626979 = 31627202
613 + 31626589 = 31627202
631 + 31626571 = 31627202
709 + 31626493 = 31627202
1009 + 31626193 = 31627202
1093 + 31626109 = 31627202
1123 + 31626079 = 31627202

Showing the first eight; more decompositions exist.
