Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656488, here are decompositions:

7 + 8656481 = 8656488
11 + 8656477 = 8656488
19 + 8656469 = 8656488
89 + 8656399 = 8656488
109 + 8656379 = 8656488
131 + 8656357 = 8656488
149 + 8656339 = 8656488
167 + 8656321 = 8656488

Showing the first eight; more decompositions exist.
