Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624746, here are decompositions:

5 + 31624741 = 31624746
7 + 31624739 = 31624746
29 + 31624717 = 31624746
47 + 31624699 = 31624746
73 + 31624673 = 31624746
103 + 31624643 = 31624746
107 + 31624639 = 31624746
149 + 31624597 = 31624746

Showing the first eight; more decompositions exist.
