Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012156, here are decompositions:

23 + 1012133 = 1012156
53 + 1012103 = 1012156
59 + 1012097 = 1012156
107 + 1012049 = 1012156
113 + 1012043 = 1012156
149 + 1012007 = 1012156
239 + 1011917 = 1012156
263 + 1011893 = 1012156

Showing the first eight; more decompositions exist.
