Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625498, here are decompositions:

31 + 31625467 = 31625498
67 + 31625431 = 31625498
97 + 31625401 = 31625498
349 + 31625149 = 31625498
367 + 31625131 = 31625498
439 + 31625059 = 31625498
547 + 31624951 = 31625498
571 + 31624927 = 31625498

Showing the first eight; more decompositions exist.
