Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495478, here are decompositions:

17 + 495461 = 495478
29 + 495449 = 495478
41 + 495437 = 495478
89 + 495389 = 495478
101 + 495377 = 495478
107 + 495371 = 495478
131 + 495347 = 495478
257 + 495221 = 495478

Showing the first eight; more decompositions exist.
