Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534528, here are decompositions:

41 + 31534487 = 31534528
71 + 31534457 = 31534528
101 + 31534427 = 31534528
227 + 31534301 = 31534528
257 + 31534271 = 31534528
281 + 31534247 = 31534528
359 + 31534169 = 31534528
449 + 31534079 = 31534528

Showing the first eight; more decompositions exist.
