Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550332, here are decompositions:

3 + 31550329 = 31550332
5 + 31550327 = 31550332
131 + 31550201 = 31550332
179 + 31550153 = 31550332
239 + 31550093 = 31550332
269 + 31550063 = 31550332
311 + 31550021 = 31550332
353 + 31549979 = 31550332

Showing the first eight; more decompositions exist.
