Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491764, here are decompositions:

17 + 491747 = 491764
113 + 491651 = 491764
131 + 491633 = 491764
137 + 491627 = 491764
173 + 491591 = 491764
227 + 491537 = 491764
233 + 491531 = 491764
263 + 491501 = 491764

Showing the first eight; more decompositions exist.
