Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550022, here are decompositions:

41 + 31549981 = 31550022
43 + 31549979 = 31550022
59 + 31549963 = 31550022
89 + 31549933 = 31550022
103 + 31549919 = 31550022
131 + 31549891 = 31550022
149 + 31549873 = 31550022
193 + 31549829 = 31550022

Showing the first eight; more decompositions exist.
