Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625936, here are decompositions:

19 + 31625917 = 31625936
157 + 31625779 = 31625936
163 + 31625773 = 31625936
283 + 31625653 = 31625936
337 + 31625599 = 31625936
373 + 31625563 = 31625936
673 + 31625263 = 31625936
757 + 31625179 = 31625936

Showing the first eight; more decompositions exist.
