Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495206, here are decompositions:

7 + 495199 = 495206
67 + 495139 = 495206
73 + 495133 = 495206
97 + 495109 = 495206
139 + 495067 = 495206
163 + 495043 = 495206
307 + 494899 = 495206
457 + 494749 = 495206

Showing the first eight; more decompositions exist.
