Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495842, here are decompositions:

13 + 495829 = 495842
43 + 495799 = 495842
73 + 495769 = 495842
163 + 495679 = 495842
223 + 495619 = 495842
229 + 495613 = 495842
271 + 495571 = 495842
283 + 495559 = 495842

Showing the first eight; more decompositions exist.
