Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542612, here are decompositions:

53 + 31542559 = 31542612
89 + 31542523 = 31542612
103 + 31542509 = 31542612
173 + 31542439 = 31542612
193 + 31542419 = 31542612
239 + 31542373 = 31542612
271 + 31542341 = 31542612
331 + 31542281 = 31542612

Showing the first eight; more decompositions exist.
