Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550050, here are decompositions:

3 + 31550047 = 31550050
23 + 31550027 = 31550050
29 + 31550021 = 31550050
71 + 31549979 = 31550050
83 + 31549967 = 31550050
131 + 31549919 = 31550050
251 + 31549799 = 31550050
269 + 31549781 = 31550050

Showing the first eight; more decompositions exist.
