Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012978, here are decompositions:

11 + 1012967 = 1012978
47 + 1012931 = 1012978
59 + 1012919 = 1012978
149 + 1012829 = 1012978
167 + 1012811 = 1012978
227 + 1012751 = 1012978
257 + 1012721 = 1012978
347 + 1012631 = 1012978

Showing the first eight; more decompositions exist.
