Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625762, here are decompositions:

31 + 31625731 = 31625762
109 + 31625653 = 31625762
163 + 31625599 = 31625762
199 + 31625563 = 31625762
331 + 31625431 = 31625762
379 + 31625383 = 31625762
499 + 31625263 = 31625762
613 + 31625149 = 31625762

Showing the first eight; more decompositions exist.
