Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022940, here are decompositions:

7 + 1022933 = 1022940
11 + 1022929 = 1022940
29 + 1022911 = 1022940
41 + 1022899 = 1022940
59 + 1022881 = 1022940
71 + 1022869 = 1022940
97 + 1022843 = 1022940
103 + 1022837 = 1022940

Showing the first eight; more decompositions exist.
