Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719620, here are decompositions:

17 + 8719603 = 8719620
29 + 8719591 = 8719620
43 + 8719577 = 8719620
47 + 8719573 = 8719620
53 + 8719567 = 8719620
71 + 8719549 = 8719620
79 + 8719541 = 8719620
101 + 8719519 = 8719620

Showing the first eight; more decompositions exist.
