Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491104, here are decompositions:

23 + 491081 = 491104
101 + 491003 = 491104
113 + 490991 = 491104
137 + 490967 = 491104
167 + 490937 = 491104
191 + 490913 = 491104
227 + 490877 = 491104
443 + 490661 = 491104

Showing the first eight; more decompositions exist.
