Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491182, here are decompositions:

11 + 491171 = 491182
23 + 491159 = 491182
53 + 491129 = 491182
101 + 491081 = 491182
179 + 491003 = 491182
191 + 490991 = 491182
233 + 490949 = 491182
269 + 490913 = 491182

Showing the first eight; more decompositions exist.
