Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660448, here are decompositions:

11 + 8660437 = 8660448
29 + 8660419 = 8660448
47 + 8660401 = 8660448
61 + 8660387 = 8660448
67 + 8660381 = 8660448
79 + 8660369 = 8660448
109 + 8660339 = 8660448
151 + 8660297 = 8660448

Showing the first eight; more decompositions exist.
