Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495446, here are decompositions:

13 + 495433 = 495446
103 + 495343 = 495446
109 + 495337 = 495446
139 + 495307 = 495446
157 + 495289 = 495446
307 + 495139 = 495446
313 + 495133 = 495446
337 + 495109 = 495446

Showing the first eight; more decompositions exist.
