Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549606, here are decompositions:

17 + 31549589 = 31549606
59 + 31549547 = 31549606
107 + 31549499 = 31549606
167 + 31549439 = 31549606
233 + 31549373 = 31549606
269 + 31549337 = 31549606
563 + 31549043 = 31549606
587 + 31549019 = 31549606

Showing the first eight; more decompositions exist.
