Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625634, here are decompositions:

17 + 31625617 = 31625634
31 + 31625603 = 31625634
67 + 31625567 = 31625634
71 + 31625563 = 31625634
97 + 31625537 = 31625634
127 + 31625507 = 31625634
167 + 31625467 = 31625634
181 + 31625453 = 31625634

Showing the first eight; more decompositions exist.
