Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028130, here are decompositions:

13 + 1028117 = 1028130
17 + 1028113 = 1028130
23 + 1028107 = 1028130
29 + 1028101 = 1028130
31 + 1028099 = 1028130
41 + 1028089 = 1028130
67 + 1028063 = 1028130
79 + 1028051 = 1028130

Showing the first eight; more decompositions exist.
