Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491716, here are decompositions:

47 + 491669 = 491716
83 + 491633 = 491716
89 + 491627 = 491716
179 + 491537 = 491716
227 + 491489 = 491716
233 + 491483 = 491716
293 + 491423 = 491716
359 + 491357 = 491716

Showing the first eight; more decompositions exist.
