Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491934, here are decompositions:

11 + 491923 = 491934
61 + 491873 = 491934
67 + 491867 = 491934
83 + 491851 = 491934
97 + 491837 = 491934
101 + 491833 = 491934
137 + 491797 = 491934
151 + 491783 = 491934

Showing the first eight; more decompositions exist.
