Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626776, here are decompositions:

67 + 31626709 = 31626776
109 + 31626667 = 31626776
157 + 31626619 = 31626776
229 + 31626547 = 31626776
277 + 31626499 = 31626776
283 + 31626493 = 31626776
409 + 31626367 = 31626776
439 + 31626337 = 31626776

Showing the first eight; more decompositions exist.
