Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624814, here are decompositions:

7 + 31624807 = 31624814
31 + 31624783 = 31624814
61 + 31624753 = 31624814
73 + 31624741 = 31624814
97 + 31624717 = 31624814
223 + 31624591 = 31624814
307 + 31624507 = 31624814
337 + 31624477 = 31624814

Showing the first eight; more decompositions exist.
