Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449460, here are decompositions:

11 + 31449449 = 31449460
59 + 31449401 = 31449460
83 + 31449377 = 31449460
101 + 31449359 = 31449460
137 + 31449323 = 31449460
173 + 31449287 = 31449460
197 + 31449263 = 31449460
227 + 31449233 = 31449460

Showing the first eight; more decompositions exist.
