Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595572, here are decompositions:

3 + 31595569 = 31595572
5 + 31595567 = 31595572
89 + 31595483 = 31595572
179 + 31595393 = 31595572
293 + 31595279 = 31595572
353 + 31595219 = 31595572
383 + 31595189 = 31595572
431 + 31595141 = 31595572

Showing the first eight; more decompositions exist.
