Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543012, here are decompositions:

3 + 31543009 = 31543012
41 + 31542971 = 31543012
71 + 31542941 = 31543012
101 + 31542911 = 31543012
131 + 31542881 = 31543012
353 + 31542659 = 31543012
503 + 31542509 = 31543012
593 + 31542419 = 31543012

Showing the first eight; more decompositions exist.
