Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595646, here are decompositions:

53 + 31595593 = 31595646
73 + 31595573 = 31595646
79 + 31595567 = 31595646
163 + 31595483 = 31595646
179 + 31595467 = 31595646
239 + 31595407 = 31595646
263 + 31595383 = 31595646
283 + 31595363 = 31595646

Showing the first eight; more decompositions exist.
