Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626056, here are decompositions:

3 + 31626053 = 31626056
37 + 31626019 = 31626056
103 + 31625953 = 31626056
139 + 31625917 = 31626056
277 + 31625779 = 31626056
283 + 31625773 = 31626056
409 + 31625647 = 31626056
439 + 31625617 = 31626056

Showing the first eight; more decompositions exist.
