Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595706, here are decompositions:

5 + 31595701 = 31595706
19 + 31595687 = 31595706
53 + 31595653 = 31595706
113 + 31595593 = 31595706
137 + 31595569 = 31595706
139 + 31595567 = 31595706
223 + 31595483 = 31595706
239 + 31595467 = 31595706

Showing the first eight; more decompositions exist.
