Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550036, here are decompositions:

73 + 31549963 = 31550036
103 + 31549933 = 31550036
139 + 31549897 = 31550036
157 + 31549879 = 31550036
163 + 31549873 = 31550036
283 + 31549753 = 31550036
307 + 31549729 = 31550036
373 + 31549663 = 31550036

Showing the first eight; more decompositions exist.
