Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495800, here are decompositions:

3 + 495797 = 495800
13 + 495787 = 495800
31 + 495769 = 495800
43 + 495757 = 495800
163 + 495637 = 495800
181 + 495619 = 495800
211 + 495589 = 495800
229 + 495571 = 495800

Showing the first eight; more decompositions exist.
