Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625706, here are decompositions:

53 + 31625653 = 31625706
59 + 31625647 = 31625706
89 + 31625617 = 31625706
103 + 31625603 = 31625706
107 + 31625599 = 31625706
127 + 31625579 = 31625706
139 + 31625567 = 31625706
197 + 31625509 = 31625706

Showing the first eight; more decompositions exist.
