Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495398, here are decompositions:

37 + 495361 = 495398
61 + 495337 = 495398
97 + 495301 = 495398
109 + 495289 = 495398
157 + 495241 = 495398
199 + 495199 = 495398
331 + 495067 = 495398
439 + 494959 = 495398

Showing the first eight; more decompositions exist.
