Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509134, here are decompositions:

43 + 31509091 = 31509134
73 + 31509061 = 31509134
103 + 31509031 = 31509134
271 + 31508863 = 31509134
277 + 31508857 = 31509134
421 + 31508713 = 31509134
457 + 31508677 = 31509134
463 + 31508671 = 31509134

Showing the first eight; more decompositions exist.
