Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624826, here are decompositions:

19 + 31624807 = 31624826
43 + 31624783 = 31624826
73 + 31624753 = 31624826
109 + 31624717 = 31624826
127 + 31624699 = 31624826
199 + 31624627 = 31624826
229 + 31624597 = 31624826
349 + 31624477 = 31624826

Showing the first eight; more decompositions exist.
