Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625696, here are decompositions:

43 + 31625653 = 31625696
79 + 31625617 = 31625696
97 + 31625599 = 31625696
229 + 31625467 = 31625696
313 + 31625383 = 31625696
433 + 31625263 = 31625696
547 + 31625149 = 31625696
757 + 31624939 = 31625696

Showing the first eight; more decompositions exist.
