Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595766, here are decompositions:

43 + 31595723 = 31595766
47 + 31595719 = 31595766
79 + 31595687 = 31595766
109 + 31595657 = 31595766
113 + 31595653 = 31595766
173 + 31595593 = 31595766
193 + 31595573 = 31595766
197 + 31595569 = 31595766

Showing the first eight; more decompositions exist.
