Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8652620, here are decompositions:

7 + 8652613 = 8652620
19 + 8652601 = 8652620
127 + 8652493 = 8652620
271 + 8652349 = 8652620
337 + 8652283 = 8652620
367 + 8652253 = 8652620
397 + 8652223 = 8652620
409 + 8652211 = 8652620

Showing the first eight; more decompositions exist.
