Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625888, here are decompositions:

67 + 31625821 = 31625888
109 + 31625779 = 31625888
127 + 31625761 = 31625888
157 + 31625731 = 31625888
241 + 31625647 = 31625888
271 + 31625617 = 31625888
379 + 31625509 = 31625888
421 + 31625467 = 31625888

Showing the first eight; more decompositions exist.
