Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491834, here are decompositions:

37 + 491797 = 491834
61 + 491773 = 491834
97 + 491737 = 491834
103 + 491731 = 491834
127 + 491707 = 491834
157 + 491677 = 491834
181 + 491653 = 491834
223 + 491611 = 491834

Showing the first eight; more decompositions exist.
