Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495318, here are decompositions:

11 + 495307 = 495318
17 + 495301 = 495318
29 + 495289 = 495318
41 + 495277 = 495318
97 + 495221 = 495318
107 + 495211 = 495318
137 + 495181 = 495318
157 + 495161 = 495318

Showing the first eight; more decompositions exist.
