Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621714, here are decompositions:

11 + 31621703 = 31621714
41 + 31621673 = 31621714
53 + 31621661 = 31621714
83 + 31621631 = 31621714
101 + 31621613 = 31621714
197 + 31621517 = 31621714
227 + 31621487 = 31621714
347 + 31621367 = 31621714

Showing the first eight; more decompositions exist.
