Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457996, here are decompositions:

7 + 31457989 = 31457996
67 + 31457929 = 31457996
127 + 31457869 = 31457996
139 + 31457857 = 31457996
277 + 31457719 = 31457996
439 + 31457557 = 31457996
547 + 31457449 = 31457996
613 + 31457383 = 31457996

Showing the first eight; more decompositions exist.
