Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495920, here are decompositions:

43 + 495877 = 495920
151 + 495769 = 495920
163 + 495757 = 495920
241 + 495679 = 495920
283 + 495637 = 495920
307 + 495613 = 495920
331 + 495589 = 495920
349 + 495571 = 495920

Showing the first eight; more decompositions exist.
