Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625060, here are decompositions:

3 + 31625057 = 31625060
109 + 31624951 = 31625060
139 + 31624921 = 31625060
199 + 31624861 = 31625060
211 + 31624849 = 31625060
223 + 31624837 = 31625060
277 + 31624783 = 31625060
307 + 31624753 = 31625060

Showing the first eight; more decompositions exist.
