Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595826, here are decompositions:

19 + 31595807 = 31595826
43 + 31595783 = 31595826
103 + 31595723 = 31595826
107 + 31595719 = 31595826
109 + 31595717 = 31595826
139 + 31595687 = 31595826
173 + 31595653 = 31595826
233 + 31595593 = 31595826

Showing the first eight; more decompositions exist.
