Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491266, here are decompositions:

5 + 491261 = 491266
47 + 491219 = 491266
53 + 491213 = 491266
107 + 491159 = 491266
137 + 491129 = 491266
227 + 491039 = 491266
263 + 491003 = 491266
317 + 490949 = 491266

Showing the first eight; more decompositions exist.
