Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491078, here are decompositions:

19 + 491059 = 491078
37 + 491041 = 491078
109 + 490969 = 491078
127 + 490951 = 491078
151 + 490927 = 491078
157 + 490921 = 491078
229 + 490849 = 491078
241 + 490837 = 491078

Showing the first eight; more decompositions exist.
