Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624994, here are decompositions:

43 + 31624951 = 31624994
67 + 31624927 = 31624994
73 + 31624921 = 31624994
157 + 31624837 = 31624994
211 + 31624783 = 31624994
241 + 31624753 = 31624994
277 + 31624717 = 31624994
367 + 31624627 = 31624994

Showing the first eight; more decompositions exist.
