Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534510, here are decompositions:

17 + 31534493 = 31534510
23 + 31534487 = 31534510
53 + 31534457 = 31534510
83 + 31534427 = 31534510
167 + 31534343 = 31534510
239 + 31534271 = 31534510
263 + 31534247 = 31534510
269 + 31534241 = 31534510

Showing the first eight; more decompositions exist.
