Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550152, here are decompositions:

3 + 31550149 = 31550152
41 + 31550111 = 31550152
59 + 31550093 = 31550152
89 + 31550063 = 31550152
131 + 31550021 = 31550152
173 + 31549979 = 31550152
233 + 31549919 = 31550152
353 + 31549799 = 31550152

Showing the first eight; more decompositions exist.
