Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491484, here are decompositions:

23 + 491461 = 491484
61 + 491423 = 491484
67 + 491417 = 491484
107 + 491377 = 491484
113 + 491371 = 491484
127 + 491357 = 491484
131 + 491353 = 491484
151 + 491333 = 491484

Showing the first eight; more decompositions exist.
