Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550282, here are decompositions:

31 + 31550251 = 31550282
61 + 31550221 = 31550282
103 + 31550179 = 31550282
151 + 31550131 = 31550282
163 + 31550119 = 31550282
349 + 31549933 = 31550282
409 + 31549873 = 31550282
619 + 31549663 = 31550282

Showing the first eight; more decompositions exist.
