Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495146, here are decompositions:

7 + 495139 = 495146
13 + 495133 = 495146
37 + 495109 = 495146
79 + 495067 = 495146
103 + 495043 = 495146
109 + 495037 = 495146
229 + 494917 = 495146
397 + 494749 = 495146

Showing the first eight; more decompositions exist.
