Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022930, here are decompositions:

19 + 1022911 = 1022930
31 + 1022899 = 1022930
61 + 1022869 = 1022930
109 + 1022821 = 1022930
157 + 1022773 = 1022930
211 + 1022719 = 1022930
229 + 1022701 = 1022930
241 + 1022689 = 1022930

Showing the first eight; more decompositions exist.
