Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045130, here are decompositions:

7 + 1045123 = 1045130
13 + 1045117 = 1045130
19 + 1045111 = 1045130
67 + 1045063 = 1045130
103 + 1045027 = 1045130
109 + 1045021 = 1045130
127 + 1045003 = 1045130
199 + 1044931 = 1045130

Showing the first eight; more decompositions exist.
