Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477050, here are decompositions:

23 + 31477027 = 31477050
29 + 31477021 = 31477050
103 + 31476947 = 31477050
179 + 31476871 = 31477050
197 + 31476853 = 31477050
229 + 31476821 = 31477050
251 + 31476799 = 31477050
307 + 31476743 = 31477050

Showing the first eight; more decompositions exist.
