Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491162, here are decompositions:

3 + 491159 = 491162
13 + 491149 = 491162
79 + 491083 = 491162
103 + 491059 = 491162
193 + 490969 = 491162
211 + 490951 = 491162
241 + 490921 = 491162
271 + 490891 = 491162

Showing the first eight; more decompositions exist.
