Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495990, here are decompositions:

7 + 495983 = 495990
17 + 495973 = 495990
23 + 495967 = 495990
31 + 495959 = 495990
37 + 495953 = 495990
43 + 495947 = 495990
59 + 495931 = 495990
67 + 495923 = 495990

Showing the first eight; more decompositions exist.
