Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022990, here are decompositions:

13 + 1022977 = 1022990
61 + 1022929 = 1022990
79 + 1022911 = 1022990
109 + 1022881 = 1022990
193 + 1022797 = 1022990
229 + 1022761 = 1022990
271 + 1022719 = 1022990
307 + 1022683 = 1022990

Showing the first eight; more decompositions exist.
