Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500666, here are decompositions:

37 + 500629 = 500666
79 + 500587 = 500666
139 + 500527 = 500666
157 + 500509 = 500666
193 + 500473 = 500666
223 + 500443 = 500666
277 + 500389 = 500666
349 + 500317 = 500666

Showing the first eight; more decompositions exist.
