Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656558, here are decompositions:

11 + 8656547 = 8656558
41 + 8656517 = 8656558
47 + 8656511 = 8656558
59 + 8656499 = 8656558
89 + 8656469 = 8656558
179 + 8656379 = 8656558
191 + 8656367 = 8656558
389 + 8656169 = 8656558

Showing the first eight; more decompositions exist.
