Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495538, here are decompositions:

11 + 495527 = 495538
47 + 495491 = 495538
89 + 495449 = 495538
101 + 495437 = 495538
137 + 495401 = 495538
149 + 495389 = 495538
167 + 495371 = 495538
179 + 495359 = 495538

Showing the first eight; more decompositions exist.
