Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625502, here are decompositions:

71 + 31625431 = 31625502
101 + 31625401 = 31625502
109 + 31625393 = 31625502
151 + 31625351 = 31625502
199 + 31625303 = 31625502
239 + 31625263 = 31625502
241 + 31625261 = 31625502
353 + 31625149 = 31625502

Showing the first eight; more decompositions exist.
