Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625864, here are decompositions:

43 + 31625821 = 31625864
97 + 31625767 = 31625864
103 + 31625761 = 31625864
211 + 31625653 = 31625864
397 + 31625467 = 31625864
433 + 31625431 = 31625864
463 + 31625401 = 31625864
601 + 31625263 = 31625864

Showing the first eight; more decompositions exist.
