Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626992, here are decompositions:

13 + 31626979 = 31626992
109 + 31626883 = 31626992
151 + 31626841 = 31626992
283 + 31626709 = 31626992
373 + 31626619 = 31626992
421 + 31626571 = 31626992
499 + 31626493 = 31626992
571 + 31626421 = 31626992

Showing the first eight; more decompositions exist.
