Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624982, here are decompositions:

3 + 31624979 = 31624982
31 + 31624951 = 31624982
43 + 31624939 = 31624982
61 + 31624921 = 31624982
199 + 31624783 = 31624982
229 + 31624753 = 31624982
241 + 31624741 = 31624982
283 + 31624699 = 31624982

Showing the first eight; more decompositions exist.
