Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595782, here are decompositions:

5 + 31595777 = 31595782
11 + 31595771 = 31595782
59 + 31595723 = 31595782
389 + 31595393 = 31595782
419 + 31595363 = 31595782
503 + 31595279 = 31595782
509 + 31595273 = 31595782
563 + 31595219 = 31595782

Showing the first eight; more decompositions exist.
