Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625468, here are decompositions:

37 + 31625431 = 31625468
67 + 31625401 = 31625468
337 + 31625131 = 31625468
409 + 31625059 = 31625468
541 + 31624927 = 31625468
547 + 31624921 = 31625468
607 + 31624861 = 31625468
619 + 31624849 = 31625468

Showing the first eight; more decompositions exist.
