Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450264, here are decompositions:

17 + 31450247 = 31450264
47 + 31450217 = 31450264
101 + 31450163 = 31450264
233 + 31450031 = 31450264
563 + 31449701 = 31450264
617 + 31449647 = 31450264
653 + 31449611 = 31450264
683 + 31449581 = 31450264

Showing the first eight; more decompositions exist.
