Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495458, here are decompositions:

37 + 495421 = 495458
97 + 495361 = 495458
151 + 495307 = 495458
157 + 495301 = 495458
181 + 495277 = 495458
277 + 495181 = 495458
307 + 495151 = 495458
349 + 495109 = 495458

Showing the first eight; more decompositions exist.
