Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009620, here are decompositions:

11 + 1009609 = 1009620
19 + 1009601 = 1009620
47 + 1009573 = 1009620
61 + 1009559 = 1009620
83 + 1009537 = 1009620
89 + 1009531 = 1009620
113 + 1009507 = 1009620
137 + 1009483 = 1009620

Showing the first eight; more decompositions exist.
