Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042540, here are decompositions:

11 + 1042529 = 1042540
17 + 1042523 = 1042540
53 + 1042487 = 1042540
71 + 1042469 = 1042540
89 + 1042451 = 1042540
101 + 1042439 = 1042540
113 + 1042427 = 1042540
167 + 1042373 = 1042540

Showing the first eight; more decompositions exist.
