Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450246, here are decompositions:

29 + 31450217 = 31450246
83 + 31450163 = 31450246
257 + 31449989 = 31450246
479 + 31449767 = 31450246
557 + 31449689 = 31450246
599 + 31449647 = 31450246
617 + 31449629 = 31450246
677 + 31449569 = 31450246

Showing the first eight; more decompositions exist.
