Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012128, here are decompositions:

31 + 1012097 = 1012128
41 + 1012087 = 1012128
79 + 1012049 = 1012128
97 + 1012031 = 1012128
149 + 1011979 = 1012128
167 + 1011961 = 1012128
181 + 1011947 = 1012128
191 + 1011937 = 1012128

Showing the first eight; more decompositions exist.
