Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029978, here are decompositions:

11 + 1029967 = 1029978
41 + 1029937 = 1029978
71 + 1029907 = 1029978
97 + 1029881 = 1029978
137 + 1029841 = 1029978
139 + 1029839 = 1029978
151 + 1029827 = 1029978
211 + 1029767 = 1029978

Showing the first eight; more decompositions exist.
