Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510646, here are decompositions:

19 + 31510627 = 31510646
43 + 31510603 = 31510646
73 + 31510573 = 31510646
157 + 31510489 = 31510646
199 + 31510447 = 31510646
283 + 31510363 = 31510646
337 + 31510309 = 31510646
733 + 31509913 = 31510646

Showing the first eight; more decompositions exist.
