Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012158, here are decompositions:

11 + 1012147 = 1012158
61 + 1012097 = 1012158
71 + 1012087 = 1012158
79 + 1012079 = 1012158
109 + 1012049 = 1012158
127 + 1012031 = 1012158
149 + 1012009 = 1012158
151 + 1012007 = 1012158

Showing the first eight; more decompositions exist.
