Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495878, here are decompositions:

79 + 495799 = 495878
109 + 495769 = 495878
127 + 495751 = 495878
199 + 495679 = 495878
211 + 495667 = 495878
241 + 495637 = 495878
307 + 495571 = 495878
367 + 495511 = 495878

Showing the first eight; more decompositions exist.
