Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495530, here are decompositions:

3 + 495527 = 495530
19 + 495511 = 495530
73 + 495457 = 495530
97 + 495433 = 495530
109 + 495421 = 495530
193 + 495337 = 495530
223 + 495307 = 495530
229 + 495301 = 495530

Showing the first eight; more decompositions exist.
