Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625648, here are decompositions:

31 + 31625617 = 31625648
139 + 31625509 = 31625648
181 + 31625467 = 31625648
367 + 31625281 = 31625648
499 + 31625149 = 31625648
709 + 31624939 = 31625648
727 + 31624921 = 31625648
787 + 31624861 = 31625648

Showing the first eight; more decompositions exist.
