Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574948, here are decompositions:

37 + 31574911 = 31574948
61 + 31574887 = 31574948
127 + 31574821 = 31574948
271 + 31574677 = 31574948
277 + 31574671 = 31574948
499 + 31574449 = 31574948
619 + 31574329 = 31574948
877 + 31574071 = 31574948

Showing the first eight; more decompositions exist.
