Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495686, here are decompositions:

7 + 495679 = 495686
19 + 495667 = 495686
67 + 495619 = 495686
73 + 495613 = 495686
97 + 495589 = 495686
127 + 495559 = 495686
229 + 495457 = 495686
349 + 495337 = 495686

Showing the first eight; more decompositions exist.
