Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624706, here are decompositions:

7 + 31624699 = 31624706
67 + 31624639 = 31624706
79 + 31624627 = 31624706
109 + 31624597 = 31624706
199 + 31624507 = 31624706
229 + 31624477 = 31624706
277 + 31624429 = 31624706
283 + 31624423 = 31624706

Showing the first eight; more decompositions exist.
