Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491554, here are decompositions:

17 + 491537 = 491554
23 + 491531 = 491554
53 + 491501 = 491554
71 + 491483 = 491554
131 + 491423 = 491554
137 + 491417 = 491554
197 + 491357 = 491554
227 + 491327 = 491554

Showing the first eight; more decompositions exist.
