Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491170, here are decompositions:

3 + 491167 = 491170
11 + 491159 = 491170
41 + 491129 = 491170
89 + 491081 = 491170
131 + 491039 = 491170
167 + 491003 = 491170
179 + 490991 = 491170
233 + 490937 = 491170

Showing the first eight; more decompositions exist.
