Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522646, here are decompositions:

13 + 31522633 = 31522646
97 + 31522549 = 31522646
283 + 31522363 = 31522646
307 + 31522339 = 31522646
349 + 31522297 = 31522646
439 + 31522207 = 31522646
853 + 31521793 = 31522646
907 + 31521739 = 31522646

Showing the first eight; more decompositions exist.
