Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624804, here are decompositions:

5 + 31624799 = 31624804
23 + 31624781 = 31624804
41 + 31624763 = 31624804
131 + 31624673 = 31624804
173 + 31624631 = 31624804
191 + 31624613 = 31624804
257 + 31624547 = 31624804
293 + 31624511 = 31624804

Showing the first eight; more decompositions exist.
