Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625410, here are decompositions:

17 + 31625393 = 31625410
29 + 31625381 = 31625410
59 + 31625351 = 31625410
107 + 31625303 = 31625410
149 + 31625261 = 31625410
263 + 31625147 = 31625410
353 + 31625057 = 31625410
431 + 31624979 = 31625410

Showing the first eight; more decompositions exist.
