Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491996, here are decompositions:

13 + 491983 = 491996
19 + 491977 = 491996
73 + 491923 = 491996
97 + 491899 = 491996
139 + 491857 = 491996
163 + 491833 = 491996
199 + 491797 = 491996
223 + 491773 = 491996

Showing the first eight; more decompositions exist.
