Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495890, here are decompositions:

13 + 495877 = 495890
61 + 495829 = 495890
103 + 495787 = 495890
139 + 495751 = 495890
211 + 495679 = 495890
223 + 495667 = 495890
271 + 495619 = 495890
277 + 495613 = 495890

Showing the first eight; more decompositions exist.
