Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567502, here are decompositions:

73 + 31567429 = 31567502
223 + 31567279 = 31567502
271 + 31567231 = 31567502
283 + 31567219 = 31567502
349 + 31567153 = 31567502
523 + 31566979 = 31567502
601 + 31566901 = 31567502
709 + 31566793 = 31567502

Showing the first eight; more decompositions exist.
