Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458056, here are decompositions:

43 + 31458013 = 31458056
67 + 31457989 = 31458056
127 + 31457929 = 31458056
199 + 31457857 = 31458056
313 + 31457743 = 31458056
337 + 31457719 = 31458056
349 + 31457707 = 31458056
499 + 31457557 = 31458056

Showing the first eight; more decompositions exist.
