Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508606, here are decompositions:

37 + 31508569 = 31508606
79 + 31508527 = 31508606
97 + 31508509 = 31508606
163 + 31508443 = 31508606
277 + 31508329 = 31508606
373 + 31508233 = 31508606
379 + 31508227 = 31508606
463 + 31508143 = 31508606

Showing the first eight; more decompositions exist.
