Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542756, here are decompositions:

29 + 31542727 = 31542756
53 + 31542703 = 31542756
59 + 31542697 = 31542756
79 + 31542677 = 31542756
97 + 31542659 = 31542756
197 + 31542559 = 31542756
233 + 31542523 = 31542756
269 + 31542487 = 31542756

Showing the first eight; more decompositions exist.
