Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450024, here are decompositions:

3 + 31450021 = 31450024
101 + 31449923 = 31450024
233 + 31449791 = 31450024
257 + 31449767 = 31450024
443 + 31449581 = 31450024
467 + 31449557 = 31450024
647 + 31449377 = 31450024
701 + 31449323 = 31450024

Showing the first eight; more decompositions exist.
