Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495858, here are decompositions:

7 + 495851 = 495858
29 + 495829 = 495858
31 + 495827 = 495858
37 + 495821 = 495858
59 + 495799 = 495858
61 + 495797 = 495858
67 + 495791 = 495858
71 + 495787 = 495858

Showing the first eight; more decompositions exist.
