Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448294, here are decompositions:

13 + 31448281 = 31448294
61 + 31448233 = 31448294
103 + 31448191 = 31448294
223 + 31448071 = 31448294
271 + 31448023 = 31448294
277 + 31448017 = 31448294
307 + 31447987 = 31448294
331 + 31447963 = 31448294

Showing the first eight; more decompositions exist.
