Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495138, here are decompositions:

5 + 495133 = 495138
19 + 495119 = 495138
29 + 495109 = 495138
67 + 495071 = 495138
71 + 495067 = 495138
97 + 495041 = 495138
101 + 495037 = 495138
151 + 494987 = 495138

Showing the first eight; more decompositions exist.
