Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565596, here are decompositions:

173 + 31565423 = 31565596
197 + 31565399 = 31565596
317 + 31565279 = 31565596
347 + 31565249 = 31565596
389 + 31565207 = 31565596
467 + 31565129 = 31565596
479 + 31565117 = 31565596
509 + 31565087 = 31565596

Showing the first eight; more decompositions exist.
