Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624864, here are decompositions:

3 + 31624861 = 31624864
83 + 31624781 = 31624864
101 + 31624763 = 31624864
191 + 31624673 = 31624864
233 + 31624631 = 31624864
251 + 31624613 = 31624864
317 + 31624547 = 31624864
353 + 31624511 = 31624864

Showing the first eight; more decompositions exist.
