Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542976, here are decompositions:

5 + 31542971 = 31542976
149 + 31542827 = 31542976
167 + 31542809 = 31542976
317 + 31542659 = 31542976
389 + 31542587 = 31542976
467 + 31542509 = 31542976
557 + 31542419 = 31542976
599 + 31542377 = 31542976

Showing the first eight; more decompositions exist.
