Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624734, here are decompositions:

17 + 31624717 = 31624734
61 + 31624673 = 31624734
73 + 31624661 = 31624734
103 + 31624631 = 31624734
107 + 31624627 = 31624734
137 + 31624597 = 31624734
223 + 31624511 = 31624734
227 + 31624507 = 31624734

Showing the first eight; more decompositions exist.
