Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491048, here are decompositions:

7 + 491041 = 491048
79 + 490969 = 491048
97 + 490951 = 491048
127 + 490921 = 491048
157 + 490891 = 491048
199 + 490849 = 491048
211 + 490837 = 491048
277 + 490771 = 491048

Showing the first eight; more decompositions exist.
