Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495824, here are decompositions:

3 + 495821 = 495824
37 + 495787 = 495824
67 + 495757 = 495824
73 + 495751 = 495824
157 + 495667 = 495824
211 + 495613 = 495824
313 + 495511 = 495824
367 + 495457 = 495824

Showing the first eight; more decompositions exist.
