Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495020, here are decompositions:

3 + 495017 = 495020
61 + 494959 = 495020
103 + 494917 = 495020
271 + 494749 = 495020
277 + 494743 = 495020
283 + 494737 = 495020
307 + 494713 = 495020
349 + 494671 = 495020

Showing the first eight; more decompositions exist.
