Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042620, here are decompositions:

11 + 1042609 = 1042620
13 + 1042607 = 1042620
23 + 1042597 = 1042620
37 + 1042583 = 1042620
43 + 1042577 = 1042620
97 + 1042523 = 1042620
101 + 1042519 = 1042620
151 + 1042469 = 1042620

Showing the first eight; more decompositions exist.
