Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625540, here are decompositions:

13 + 8625527 = 8625540
19 + 8625521 = 8625540
23 + 8625517 = 8625540
31 + 8625509 = 8625540
47 + 8625493 = 8625540
61 + 8625479 = 8625540
73 + 8625467 = 8625540
89 + 8625451 = 8625540

Showing the first eight; more decompositions exist.
