Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656398, here are decompositions:

5 + 8656393 = 8656398
19 + 8656379 = 8656398
29 + 8656369 = 8656398
31 + 8656367 = 8656398
41 + 8656357 = 8656398
59 + 8656339 = 8656398
167 + 8656231 = 8656398
227 + 8656171 = 8656398

Showing the first eight; more decompositions exist.
