Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626968, here are decompositions:

127 + 31626841 = 31626968
181 + 31626787 = 31626968
277 + 31626691 = 31626968
349 + 31626619 = 31626968
379 + 31626589 = 31626968
397 + 31626571 = 31626968
421 + 31626547 = 31626968
487 + 31626481 = 31626968

Showing the first eight; more decompositions exist.
