Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656480, here are decompositions:

3 + 8656477 = 8656480
11 + 8656469 = 8656480
17 + 8656463 = 8656480
47 + 8656433 = 8656480
101 + 8656379 = 8656480
113 + 8656367 = 8656480
167 + 8656313 = 8656480
197 + 8656283 = 8656480

Showing the first eight; more decompositions exist.
