Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491108, here are decompositions:

67 + 491041 = 491108
139 + 490969 = 491108
151 + 490957 = 491108
157 + 490951 = 491108
181 + 490927 = 491108
271 + 490837 = 491108
337 + 490771 = 491108
367 + 490741 = 491108

Showing the first eight; more decompositions exist.
