Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449294, here are decompositions:

5 + 31449289 = 31449294
7 + 31449287 = 31449294
31 + 31449263 = 31449294
47 + 31449247 = 31449294
53 + 31449241 = 31449294
61 + 31449233 = 31449294
103 + 31449191 = 31449294
131 + 31449163 = 31449294

Showing the first eight; more decompositions exist.
