Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626512, here are decompositions:

13 + 31626499 = 31626512
19 + 31626493 = 31626512
31 + 31626481 = 31626512
283 + 31626229 = 31626512
433 + 31626079 = 31626512
439 + 31626073 = 31626512
601 + 31625911 = 31626512
691 + 31625821 = 31626512

Showing the first eight; more decompositions exist.
