Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626914, here are decompositions:

31 + 31626883 = 31626914
73 + 31626841 = 31626914
127 + 31626787 = 31626914
223 + 31626691 = 31626914
307 + 31626607 = 31626914
367 + 31626547 = 31626914
421 + 31626493 = 31626914
433 + 31626481 = 31626914

Showing the first eight; more decompositions exist.
