Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015112, here are decompositions:

19 + 1015093 = 1015112
31 + 1015081 = 1015112
61 + 1015051 = 1015112
73 + 1015039 = 1015112
103 + 1015009 = 1015112
139 + 1014973 = 1015112
223 + 1014889 = 1015112
349 + 1014763 = 1015112

Showing the first eight; more decompositions exist.
