Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624704, here are decompositions:

5 + 31624699 = 31624704
31 + 31624673 = 31624704
43 + 31624661 = 31624704
61 + 31624643 = 31624704
73 + 31624631 = 31624704
107 + 31624597 = 31624704
113 + 31624591 = 31624704
157 + 31624547 = 31624704

Showing the first eight; more decompositions exist.
