Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550254, here are decompositions:

3 + 31550251 = 31550254
41 + 31550213 = 31550254
53 + 31550201 = 31550254
101 + 31550153 = 31550254
191 + 31550063 = 31550254
227 + 31550027 = 31550254
233 + 31550021 = 31550254
503 + 31549751 = 31550254

Showing the first eight; more decompositions exist.
