Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495226, here are decompositions:

5 + 495221 = 495226
107 + 495119 = 495226
113 + 495113 = 495226
239 + 494987 = 495226
293 + 494933 = 495226
353 + 494873 = 495226
383 + 494843 = 495226
443 + 494783 = 495226

Showing the first eight; more decompositions exist.
