Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625048, here are decompositions:

97 + 31624951 = 31625048
109 + 31624939 = 31625048
127 + 31624921 = 31625048
199 + 31624849 = 31625048
211 + 31624837 = 31625048
241 + 31624807 = 31625048
307 + 31624741 = 31625048
331 + 31624717 = 31625048

Showing the first eight; more decompositions exist.
