Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534686, here are decompositions:

17 + 31534669 = 31534686
89 + 31534597 = 31534686
97 + 31534589 = 31534686
193 + 31534493 = 31534686
199 + 31534487 = 31534686
229 + 31534457 = 31534686
257 + 31534429 = 31534686
263 + 31534423 = 31534686

Showing the first eight; more decompositions exist.
