Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550162, here are decompositions:

13 + 31550149 = 31550162
31 + 31550131 = 31550162
43 + 31550119 = 31550162
181 + 31549981 = 31550162
199 + 31549963 = 31550162
229 + 31549933 = 31550162
271 + 31549891 = 31550162
283 + 31549879 = 31550162

Showing the first eight; more decompositions exist.
