Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626746, here are decompositions:

37 + 31626709 = 31626746
79 + 31626667 = 31626746
127 + 31626619 = 31626746
139 + 31626607 = 31626746
157 + 31626589 = 31626746
199 + 31626547 = 31626746
379 + 31626367 = 31626746
409 + 31626337 = 31626746

Showing the first eight; more decompositions exist.
