Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487462, here are decompositions:

43 + 31487419 = 31487462
151 + 31487311 = 31487462
199 + 31487263 = 31487462
211 + 31487251 = 31487462
229 + 31487233 = 31487462
463 + 31486999 = 31487462
739 + 31486723 = 31487462
751 + 31486711 = 31487462

Showing the first eight; more decompositions exist.
