Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491844, here are decompositions:

7 + 491837 = 491844
11 + 491833 = 491844
47 + 491797 = 491844
61 + 491783 = 491844
71 + 491773 = 491844
97 + 491747 = 491844
107 + 491737 = 491844
113 + 491731 = 491844

Showing the first eight; more decompositions exist.
