Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495236, here are decompositions:

37 + 495199 = 495236
97 + 495139 = 495236
103 + 495133 = 495236
127 + 495109 = 495236
193 + 495043 = 495236
199 + 495037 = 495236
277 + 494959 = 495236
337 + 494899 = 495236

Showing the first eight; more decompositions exist.
