Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491922, here are decompositions:

23 + 491899 = 491922
71 + 491851 = 491922
89 + 491833 = 491922
103 + 491819 = 491922
139 + 491783 = 491922
149 + 491773 = 491922
191 + 491731 = 491922
269 + 491653 = 491922

Showing the first eight; more decompositions exist.
