Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020130, here are decompositions:

17 + 1020113 = 1020130
29 + 1020101 = 1020130
53 + 1020077 = 1020130
71 + 1020059 = 1020130
107 + 1020023 = 1020130
227 + 1019903 = 1020130
257 + 1019873 = 1020130
269 + 1019861 = 1020130

Showing the first eight; more decompositions exist.
