Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624958, here are decompositions:

7 + 31624951 = 31624958
19 + 31624939 = 31624958
31 + 31624927 = 31624958
37 + 31624921 = 31624958
97 + 31624861 = 31624958
109 + 31624849 = 31624958
151 + 31624807 = 31624958
241 + 31624717 = 31624958

Showing the first eight; more decompositions exist.
