Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005978, here are decompositions:

7 + 1005971 = 1005978
19 + 1005959 = 1005978
41 + 1005937 = 1005978
47 + 1005931 = 1005978
67 + 1005911 = 1005978
151 + 1005827 = 1005978
157 + 1005821 = 1005978
227 + 1005751 = 1005978

Showing the first eight; more decompositions exist.
