Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485122, here are decompositions:

43 + 31485079 = 31485122
73 + 31485049 = 31485122
103 + 31485019 = 31485122
181 + 31484941 = 31485122
211 + 31484911 = 31485122
283 + 31484839 = 31485122
619 + 31484503 = 31485122
661 + 31484461 = 31485122

Showing the first eight; more decompositions exist.
