Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471502, here are decompositions:

331 + 31471171 = 31471502
379 + 31471123 = 31471502
409 + 31471093 = 31471502
613 + 31470889 = 31471502
709 + 31470793 = 31471502
883 + 31470619 = 31471502
1033 + 31470469 = 31471502
1093 + 31470409 = 31471502

Showing the first eight; more decompositions exist.
