Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625774, here are decompositions:

7 + 31625767 = 31625774
13 + 31625761 = 31625774
43 + 31625731 = 31625774
127 + 31625647 = 31625774
157 + 31625617 = 31625774
211 + 31625563 = 31625774
307 + 31625467 = 31625774
373 + 31625401 = 31625774

Showing the first eight; more decompositions exist.
