Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491106, here are decompositions:

23 + 491083 = 491106
47 + 491059 = 491106
67 + 491039 = 491106
103 + 491003 = 491106
113 + 490993 = 491106
137 + 490969 = 491106
139 + 490967 = 491106
149 + 490957 = 491106

Showing the first eight; more decompositions exist.
