Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625476, here are decompositions:

23 + 31625453 = 31625476
83 + 31625393 = 31625476
173 + 31625303 = 31625476
419 + 31625057 = 31625476
569 + 31624907 = 31625476
647 + 31624829 = 31625476
677 + 31624799 = 31625476
863 + 31624613 = 31625476

Showing the first eight; more decompositions exist.
