Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495500, here are decompositions:

43 + 495457 = 495500
67 + 495433 = 495500
79 + 495421 = 495500
139 + 495361 = 495500
157 + 495343 = 495500
163 + 495337 = 495500
193 + 495307 = 495500
199 + 495301 = 495500

Showing the first eight; more decompositions exist.
