Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624926, here are decompositions:

5 + 31624921 = 31624926
19 + 31624907 = 31624926
89 + 31624837 = 31624926
97 + 31624829 = 31624926
127 + 31624799 = 31624926
163 + 31624763 = 31624926
173 + 31624753 = 31624926
227 + 31624699 = 31624926

Showing the first eight; more decompositions exist.
