Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625682, here are decompositions:

29 + 31625653 = 31625682
31 + 31625651 = 31625682
79 + 31625603 = 31625682
83 + 31625599 = 31625682
103 + 31625579 = 31625682
173 + 31625509 = 31625682
229 + 31625453 = 31625682
251 + 31625431 = 31625682

Showing the first eight; more decompositions exist.
