Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012178, here are decompositions:

7 + 1012171 = 1012178
19 + 1012159 = 1012178
31 + 1012147 = 1012178
199 + 1011979 = 1012178
241 + 1011937 = 1012178
379 + 1011799 = 1012178
547 + 1011631 = 1012178
577 + 1011601 = 1012178

Showing the first eight; more decompositions exist.
