Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476540, here are decompositions:

23 + 31476517 = 31476540
31 + 31476509 = 31476540
41 + 31476499 = 31476540
79 + 31476461 = 31476540
83 + 31476457 = 31476540
89 + 31476451 = 31476540
103 + 31476437 = 31476540
107 + 31476433 = 31476540

Showing the first eight; more decompositions exist.
