Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449304, here are decompositions:

17 + 31449287 = 31449304
41 + 31449263 = 31449304
71 + 31449233 = 31449304
113 + 31449191 = 31449304
233 + 31449071 = 31449304
251 + 31449053 = 31449304
317 + 31448987 = 31449304
401 + 31448903 = 31449304

Showing the first eight; more decompositions exist.
