Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625426, here are decompositions:

43 + 31625383 = 31625426
163 + 31625263 = 31625426
277 + 31625149 = 31625426
367 + 31625059 = 31625426
487 + 31624939 = 31625426
499 + 31624927 = 31625426
577 + 31624849 = 31625426
619 + 31624807 = 31625426

Showing the first eight; more decompositions exist.
