Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491046, here are decompositions:

5 + 491041 = 491046
7 + 491039 = 491046
43 + 491003 = 491046
53 + 490993 = 491046
79 + 490967 = 491046
89 + 490957 = 491046
97 + 490949 = 491046
109 + 490937 = 491046

Showing the first eight; more decompositions exist.
