Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625460, here are decompositions:

7 + 31625453 = 31625460
29 + 31625431 = 31625460
59 + 31625401 = 31625460
67 + 31625393 = 31625460
79 + 31625381 = 31625460
109 + 31625351 = 31625460
157 + 31625303 = 31625460
179 + 31625281 = 31625460

Showing the first eight; more decompositions exist.
