Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022978, here are decompositions:

67 + 1022911 = 1022978
79 + 1022899 = 1022978
97 + 1022881 = 1022978
109 + 1022869 = 1022978
157 + 1022821 = 1022978
181 + 1022797 = 1022978
277 + 1022701 = 1022978
349 + 1022629 = 1022978

Showing the first eight; more decompositions exist.
