Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028112, here are decompositions:

5 + 1028107 = 1028112
11 + 1028101 = 1028112
13 + 1028099 = 1028112
23 + 1028089 = 1028112
31 + 1028081 = 1028112
61 + 1028051 = 1028112
83 + 1028029 = 1028112
89 + 1028023 = 1028112

Showing the first eight; more decompositions exist.
