Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495290, here are decompositions:

13 + 495277 = 495290
79 + 495211 = 495290
109 + 495181 = 495290
139 + 495151 = 495290
151 + 495139 = 495290
157 + 495133 = 495290
181 + 495109 = 495290
223 + 495067 = 495290

Showing the first eight; more decompositions exist.
