Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626758, here are decompositions:

67 + 31626691 = 31626758
139 + 31626619 = 31626758
151 + 31626607 = 31626758
211 + 31626547 = 31626758
277 + 31626481 = 31626758
337 + 31626421 = 31626758
421 + 31626337 = 31626758
739 + 31626019 = 31626758

Showing the first eight; more decompositions exist.
