Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485032, here are decompositions:

13 + 31485019 = 31485032
31 + 31485001 = 31485032
43 + 31484989 = 31485032
193 + 31484839 = 31485032
211 + 31484821 = 31485032
463 + 31484569 = 31485032
499 + 31484533 = 31485032
571 + 31484461 = 31485032

Showing the first eight; more decompositions exist.
