Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627502, here are decompositions:

19 + 31627483 = 31627502
199 + 31627303 = 31627502
241 + 31627261 = 31627502
433 + 31627069 = 31627502
523 + 31626979 = 31627502
619 + 31626883 = 31627502
661 + 31626841 = 31627502
811 + 31626691 = 31627502

Showing the first eight; more decompositions exist.
