Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495078, here are decompositions:

7 + 495071 = 495078
11 + 495067 = 495078
37 + 495041 = 495078
41 + 495037 = 495078
61 + 495017 = 495078
139 + 494939 = 495078
151 + 494927 = 495078
179 + 494899 = 495078

Showing the first eight; more decompositions exist.
