Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007978, here are decompositions:

7 + 1007971 = 1007978
19 + 1007959 = 1007978
151 + 1007827 = 1007978
211 + 1007767 = 1007978
229 + 1007749 = 1007978
277 + 1007701 = 1007978
331 + 1007647 = 1007978
379 + 1007599 = 1007978

Showing the first eight; more decompositions exist.
