Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660912, here are decompositions:

3 + 8660909 = 8660912
223 + 8660689 = 8660912
229 + 8660683 = 8660912
241 + 8660671 = 8660912
373 + 8660539 = 8660912
409 + 8660503 = 8660912
499 + 8660413 = 8660912
643 + 8660269 = 8660912

Showing the first eight; more decompositions exist.
