Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491822, here are decompositions:

3 + 491819 = 491822
103 + 491719 = 491822
211 + 491611 = 491822
229 + 491593 = 491822
241 + 491581 = 491822
283 + 491539 = 491822
523 + 491299 = 491822
571 + 491251 = 491822

Showing the first eight; more decompositions exist.
