Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449704, here are decompositions:

3 + 31449701 = 31449704
7 + 31449697 = 31449704
31 + 31449673 = 31449704
67 + 31449637 = 31449704
127 + 31449577 = 31449704
151 + 31449553 = 31449704
211 + 31449493 = 31449704
241 + 31449463 = 31449704

Showing the first eight; more decompositions exist.
