Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625654, here are decompositions:

3 + 31625651 = 31625654
7 + 31625647 = 31625654
37 + 31625617 = 31625654
223 + 31625431 = 31625654
271 + 31625383 = 31625654
373 + 31625281 = 31625654
523 + 31625131 = 31625654
727 + 31624927 = 31625654

Showing the first eight; more decompositions exist.
