Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491884, here are decompositions:

11 + 491873 = 491884
17 + 491867 = 491884
47 + 491837 = 491884
101 + 491783 = 491884
137 + 491747 = 491884
233 + 491651 = 491884
251 + 491633 = 491884
257 + 491627 = 491884

Showing the first eight; more decompositions exist.
