Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022810, here are decompositions:

13 + 1022797 = 1022810
37 + 1022773 = 1022810
109 + 1022701 = 1022810
127 + 1022683 = 1022810
157 + 1022653 = 1022810
181 + 1022629 = 1022810
199 + 1022611 = 1022810
307 + 1022503 = 1022810

Showing the first eight; more decompositions exist.
