Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495566, here are decompositions:

3 + 495563 = 495566
7 + 495559 = 495566
109 + 495457 = 495566
223 + 495343 = 495566
229 + 495337 = 495566
277 + 495289 = 495566
367 + 495199 = 495566
433 + 495133 = 495566

Showing the first eight; more decompositions exist.
