Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491022, here are decompositions:

19 + 491003 = 491022
29 + 490993 = 491022
31 + 490991 = 491022
53 + 490969 = 491022
71 + 490951 = 491022
73 + 490949 = 491022
101 + 490921 = 491022
109 + 490913 = 491022

Showing the first eight; more decompositions exist.
