Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625010, here are decompositions:

31 + 31624979 = 31625010
59 + 31624951 = 31625010
71 + 31624939 = 31625010
83 + 31624927 = 31625010
89 + 31624921 = 31625010
103 + 31624907 = 31625010
149 + 31624861 = 31625010
173 + 31624837 = 31625010

Showing the first eight; more decompositions exist.
