Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495266, here are decompositions:

67 + 495199 = 495266
127 + 495139 = 495266
157 + 495109 = 495266
199 + 495067 = 495266
223 + 495043 = 495266
229 + 495037 = 495266
307 + 494959 = 495266
349 + 494917 = 495266

Showing the first eight; more decompositions exist.
