Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491896, here are decompositions:

23 + 491873 = 491896
29 + 491867 = 491896
59 + 491837 = 491896
107 + 491789 = 491896
113 + 491783 = 491896
149 + 491747 = 491896
227 + 491669 = 491896
257 + 491639 = 491896

Showing the first eight; more decompositions exist.
