Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626956, here are decompositions:

13 + 31626943 = 31626956
73 + 31626883 = 31626956
337 + 31626619 = 31626956
349 + 31626607 = 31626956
367 + 31626589 = 31626956
409 + 31626547 = 31626956
457 + 31626499 = 31626956
463 + 31626493 = 31626956

Showing the first eight; more decompositions exist.
