Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534504, here are decompositions:

3 + 31534501 = 31534504
11 + 31534493 = 31534504
17 + 31534487 = 31534504
47 + 31534457 = 31534504
233 + 31534271 = 31534504
257 + 31534247 = 31534504
263 + 31534241 = 31534504
317 + 31534187 = 31534504

Showing the first eight; more decompositions exist.
