Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495200, here are decompositions:

19 + 495181 = 495200
61 + 495139 = 495200
67 + 495133 = 495200
157 + 495043 = 495200
163 + 495037 = 495200
241 + 494959 = 495200
283 + 494917 = 495200
397 + 494803 = 495200

Showing the first eight; more decompositions exist.
