Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595784, here are decompositions:

7 + 31595777 = 31595784
13 + 31595771 = 31595784
53 + 31595731 = 31595784
61 + 31595723 = 31595784
67 + 31595717 = 31595784
83 + 31595701 = 31595784
97 + 31595687 = 31595784
113 + 31595671 = 31595784

Showing the first eight; more decompositions exist.
