Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625882, here are decompositions:

61 + 31625821 = 31625882
103 + 31625779 = 31625882
109 + 31625773 = 31625882
151 + 31625731 = 31625882
229 + 31625653 = 31625882
283 + 31625599 = 31625882
373 + 31625509 = 31625882
499 + 31625383 = 31625882

Showing the first eight; more decompositions exist.
