Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495830, here are decompositions:

3 + 495827 = 495830
31 + 495799 = 495830
43 + 495787 = 495830
61 + 495769 = 495830
73 + 495757 = 495830
79 + 495751 = 495830
151 + 495679 = 495830
163 + 495667 = 495830

Showing the first eight; more decompositions exist.
