Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625364, here are decompositions:

13 + 31625351 = 31625364
61 + 31625303 = 31625364
83 + 31625281 = 31625364
101 + 31625263 = 31625364
103 + 31625261 = 31625364
233 + 31625131 = 31625364
307 + 31625057 = 31625364
443 + 31624921 = 31625364

Showing the first eight; more decompositions exist.
