Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577596, here are decompositions:

3 + 31577593 = 31577596
5 + 31577591 = 31577596
179 + 31577417 = 31577596
227 + 31577369 = 31577596
233 + 31577363 = 31577596
467 + 31577129 = 31577596
587 + 31577009 = 31577596
647 + 31576949 = 31577596

Showing the first eight; more decompositions exist.
