Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534732, here are decompositions:

3 + 31534729 = 31534732
23 + 31534709 = 31534732
41 + 31534691 = 31534732
101 + 31534631 = 31534732
179 + 31534553 = 31534732
239 + 31534493 = 31534732
389 + 31534343 = 31534732
431 + 31534301 = 31534732

Showing the first eight; more decompositions exist.
