Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491176, here are decompositions:

5 + 491171 = 491176
17 + 491159 = 491176
47 + 491129 = 491176
137 + 491039 = 491176
173 + 491003 = 491176
227 + 490949 = 491176
239 + 490937 = 491176
263 + 490913 = 491176

Showing the first eight; more decompositions exist.
