Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626998, here are decompositions:

19 + 31626979 = 31626998
31 + 31626967 = 31626998
157 + 31626841 = 31626998
211 + 31626787 = 31626998
307 + 31626691 = 31626998
331 + 31626667 = 31626998
379 + 31626619 = 31626998
409 + 31626589 = 31626998

Showing the first eight; more decompositions exist.
