Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028154, here are decompositions:

5 + 1028149 = 1028154
13 + 1028141 = 1028154
37 + 1028117 = 1028154
41 + 1028113 = 1028154
47 + 1028107 = 1028154
53 + 1028101 = 1028154
73 + 1028081 = 1028154
103 + 1028051 = 1028154

Showing the first eight; more decompositions exist.
