Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042530, here are decompositions:

7 + 1042523 = 1042530
11 + 1042519 = 1042530
43 + 1042487 = 1042530
61 + 1042469 = 1042530
79 + 1042451 = 1042530
103 + 1042427 = 1042530
131 + 1042399 = 1042530
149 + 1042381 = 1042530

Showing the first eight; more decompositions exist.
