Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495980, here are decompositions:

7 + 495973 = 495980
13 + 495967 = 495980
103 + 495877 = 495980
151 + 495829 = 495980
181 + 495799 = 495980
193 + 495787 = 495980
211 + 495769 = 495980
223 + 495757 = 495980

Showing the first eight; more decompositions exist.
