Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595586, here are decompositions:

5 + 31595581 = 31595586
13 + 31595573 = 31595586
17 + 31595569 = 31595586
19 + 31595567 = 31595586
103 + 31595483 = 31595586
179 + 31595407 = 31595586
193 + 31595393 = 31595586
199 + 31595387 = 31595586

Showing the first eight; more decompositions exist.
