Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625504, here are decompositions:

37 + 31625467 = 31625504
73 + 31625431 = 31625504
103 + 31625401 = 31625504
223 + 31625281 = 31625504
241 + 31625263 = 31625504
373 + 31625131 = 31625504
577 + 31624927 = 31625504
643 + 31624861 = 31625504

Showing the first eight; more decompositions exist.
