Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495942, here are decompositions:

11 + 495931 = 495942
19 + 495923 = 495942
43 + 495899 = 495942
113 + 495829 = 495942
151 + 495791 = 495942
173 + 495769 = 495942
191 + 495751 = 495942
193 + 495749 = 495942

Showing the first eight; more decompositions exist.
