Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621064, here are decompositions:

31 + 31621033 = 31621064
37 + 31621027 = 31621064
127 + 31620937 = 31621064
193 + 31620871 = 31621064
271 + 31620793 = 31621064
313 + 31620751 = 31621064
331 + 31620733 = 31621064
463 + 31620601 = 31621064

Showing the first eight; more decompositions exist.
