Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624674, here are decompositions:

13 + 31624661 = 31624674
31 + 31624643 = 31624674
43 + 31624631 = 31624674
47 + 31624627 = 31624674
61 + 31624613 = 31624674
83 + 31624591 = 31624674
127 + 31624547 = 31624674
163 + 31624511 = 31624674

Showing the first eight; more decompositions exist.
