Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045128, here are decompositions:

5 + 1045123 = 1045128
11 + 1045117 = 1045128
17 + 1045111 = 1045128
47 + 1045081 = 1045128
67 + 1045061 = 1045128
101 + 1045027 = 1045128
107 + 1045021 = 1045128
131 + 1044997 = 1045128

Showing the first eight; more decompositions exist.
