Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449934, here are decompositions:

3 + 31449931 = 31449934
11 + 31449923 = 31449934
167 + 31449767 = 31449934
233 + 31449701 = 31449934
353 + 31449581 = 31449934
557 + 31449377 = 31449934
647 + 31449287 = 31449934
701 + 31449233 = 31449934

Showing the first eight; more decompositions exist.
