Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595776, here are decompositions:

5 + 31595771 = 31595776
53 + 31595723 = 31595776
59 + 31595717 = 31595776
89 + 31595687 = 31595776
293 + 31595483 = 31595776
383 + 31595393 = 31595776
389 + 31595387 = 31595776
503 + 31595273 = 31595776

Showing the first eight; more decompositions exist.
