Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495308, here are decompositions:

7 + 495301 = 495308
19 + 495289 = 495308
31 + 495277 = 495308
67 + 495241 = 495308
97 + 495211 = 495308
109 + 495199 = 495308
127 + 495181 = 495308
157 + 495151 = 495308

Showing the first eight; more decompositions exist.
