Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491050, here are decompositions:

11 + 491039 = 491050
47 + 491003 = 491050
59 + 490991 = 491050
83 + 490967 = 491050
101 + 490949 = 491050
113 + 490937 = 491050
137 + 490913 = 491050
173 + 490877 = 491050

Showing the first eight; more decompositions exist.
