Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550094, here are decompositions:

31 + 31550063 = 31550094
47 + 31550047 = 31550094
67 + 31550027 = 31550094
73 + 31550021 = 31550094
113 + 31549981 = 31550094
127 + 31549967 = 31550094
131 + 31549963 = 31550094
197 + 31549897 = 31550094

Showing the first eight; more decompositions exist.
