Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499666, here are decompositions:

7 + 31499659 = 31499666
67 + 31499599 = 31499666
73 + 31499593 = 31499666
199 + 31499467 = 31499666
283 + 31499383 = 31499666
337 + 31499329 = 31499666
439 + 31499227 = 31499666
643 + 31499023 = 31499666

Showing the first eight; more decompositions exist.
