Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624916, here are decompositions:

67 + 31624849 = 31624916
79 + 31624837 = 31624916
109 + 31624807 = 31624916
163 + 31624753 = 31624916
199 + 31624717 = 31624916
277 + 31624639 = 31624916
409 + 31624507 = 31624916
439 + 31624477 = 31624916

Showing the first eight; more decompositions exist.
