Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022980, here are decompositions:

3 + 1022977 = 1022980
17 + 1022963 = 1022980
47 + 1022933 = 1022980
89 + 1022891 = 1022980
131 + 1022849 = 1022980
137 + 1022843 = 1022980
251 + 1022729 = 1022980
347 + 1022633 = 1022980

Showing the first eight; more decompositions exist.
