Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625486, here are decompositions:

19 + 31625467 = 31625486
103 + 31625383 = 31625486
223 + 31625263 = 31625486
307 + 31625179 = 31625486
337 + 31625149 = 31625486
547 + 31624939 = 31625486
733 + 31624753 = 31625486
769 + 31624717 = 31625486

Showing the first eight; more decompositions exist.
