Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491960, here are decompositions:

37 + 491923 = 491960
61 + 491899 = 491960
103 + 491857 = 491960
109 + 491851 = 491960
127 + 491833 = 491960
163 + 491797 = 491960
223 + 491737 = 491960
229 + 491731 = 491960

Showing the first eight; more decompositions exist.
