Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491054, here are decompositions:

13 + 491041 = 491054
61 + 490993 = 491054
97 + 490957 = 491054
103 + 490951 = 491054
127 + 490927 = 491054
163 + 490891 = 491054
271 + 490783 = 491054
283 + 490771 = 491054

Showing the first eight; more decompositions exist.
