Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659928, here are decompositions:

7 + 8659921 = 8659928
19 + 8659909 = 8659928
61 + 8659867 = 8659928
181 + 8659747 = 8659928
397 + 8659531 = 8659928
457 + 8659471 = 8659928
547 + 8659381 = 8659928
577 + 8659351 = 8659928

Showing the first eight; more decompositions exist.
