Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595650, here are decompositions:

83 + 31595567 = 31595650
167 + 31595483 = 31595650
257 + 31595393 = 31595650
263 + 31595387 = 31595650
431 + 31595219 = 31595650
461 + 31595189 = 31595650
509 + 31595141 = 31595650
587 + 31595063 = 31595650

Showing the first eight; more decompositions exist.
