Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626942, here are decompositions:

43 + 31626899 = 31626942
59 + 31626883 = 31626942
73 + 31626869 = 31626942
101 + 31626841 = 31626942
103 + 31626839 = 31626942
233 + 31626709 = 31626942
251 + 31626691 = 31626942
353 + 31626589 = 31626942

Showing the first eight; more decompositions exist.
