Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625708, here are decompositions:

61 + 31625647 = 31625708
109 + 31625599 = 31625708
199 + 31625509 = 31625708
241 + 31625467 = 31625708
277 + 31625431 = 31625708
307 + 31625401 = 31625708
577 + 31625131 = 31625708
757 + 31624951 = 31625708

Showing the first eight; more decompositions exist.
