Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030128, here are decompositions:

7 + 1030121 = 1030128
17 + 1030111 = 1030128
37 + 1030091 = 1030128
59 + 1030069 = 1030128
61 + 1030067 = 1030128
67 + 1030061 = 1030128
79 + 1030049 = 1030128
89 + 1030039 = 1030128

Showing the first eight; more decompositions exist.
