Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045530, here are decompositions:

7 + 1045523 = 1045530
23 + 1045507 = 1045530
37 + 1045493 = 1045530
43 + 1045487 = 1045530
61 + 1045469 = 1045530
103 + 1045427 = 1045530
107 + 1045423 = 1045530
137 + 1045393 = 1045530

Showing the first eight; more decompositions exist.
