Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450366, here are decompositions:

53 + 31450313 = 31450366
149 + 31450217 = 31450366
263 + 31450103 = 31450366
443 + 31449923 = 31450366
599 + 31449767 = 31450366
677 + 31449689 = 31450366
719 + 31449647 = 31450366
797 + 31449569 = 31450366

Showing the first eight; more decompositions exist.
