Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625792, here are decompositions:

13 + 31625779 = 31625792
19 + 31625773 = 31625792
31 + 31625761 = 31625792
61 + 31625731 = 31625792
139 + 31625653 = 31625792
193 + 31625599 = 31625792
229 + 31625563 = 31625792
283 + 31625509 = 31625792

Showing the first eight; more decompositions exist.
