Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491936, here are decompositions:

13 + 491923 = 491936
37 + 491899 = 491936
79 + 491857 = 491936
103 + 491833 = 491936
139 + 491797 = 491936
163 + 491773 = 491936
199 + 491737 = 491936
229 + 491707 = 491936

Showing the first eight; more decompositions exist.
