Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022972, here are decompositions:

43 + 1022929 = 1022972
61 + 1022911 = 1022972
73 + 1022899 = 1022972
103 + 1022869 = 1022972
151 + 1022821 = 1022972
199 + 1022773 = 1022972
211 + 1022761 = 1022972
271 + 1022701 = 1022972

Showing the first eight; more decompositions exist.
