Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625728, here are decompositions:

19 + 8625709 = 8625728
79 + 8625649 = 8625728
211 + 8625517 = 8625728
277 + 8625451 = 8625728
379 + 8625349 = 8625728
439 + 8625289 = 8625728
499 + 8625229 = 8625728
541 + 8625187 = 8625728

Showing the first eight; more decompositions exist.
