Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507866, here are decompositions:

109 + 507757 = 507866
193 + 507673 = 507866
199 + 507667 = 507866
277 + 507589 = 507866
367 + 507499 = 507866
577 + 507289 = 507866
673 + 507193 = 507866
727 + 507139 = 507866

Showing the first eight; more decompositions exist.
