Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565764, here are decompositions:

3 + 31565761 = 31565764
71 + 31565693 = 31565764
101 + 31565663 = 31565764
353 + 31565411 = 31565764
467 + 31565297 = 31565764
557 + 31565207 = 31565764
647 + 31565117 = 31565764
677 + 31565087 = 31565764

Showing the first eight; more decompositions exist.
