Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550002, here are decompositions:

23 + 31549979 = 31550002
83 + 31549919 = 31550002
173 + 31549829 = 31550002
251 + 31549751 = 31550002
269 + 31549733 = 31550002
311 + 31549691 = 31550002
353 + 31549649 = 31550002
503 + 31549499 = 31550002

Showing the first eight; more decompositions exist.
