Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002156, here are decompositions:

5 + 1002151 = 1002156
7 + 1002149 = 1002156
13 + 1002143 = 1002156
47 + 1002109 = 1002156
73 + 1002083 = 1002156
79 + 1002077 = 1002156
83 + 1002073 = 1002156
107 + 1002049 = 1002156

Showing the first eight; more decompositions exist.
