Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550252, here are decompositions:

31 + 31550221 = 31550252
73 + 31550179 = 31550252
103 + 31550149 = 31550252
271 + 31549981 = 31550252
373 + 31549879 = 31550252
379 + 31549873 = 31550252
499 + 31549753 = 31550252
523 + 31549729 = 31550252

Showing the first eight; more decompositions exist.
