Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495042, here are decompositions:

5 + 495037 = 495042
83 + 494959 = 495042
103 + 494939 = 495042
109 + 494933 = 495042
139 + 494903 = 495042
193 + 494849 = 495042
199 + 494843 = 495042
239 + 494803 = 495042

Showing the first eight; more decompositions exist.
