Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656198, here are decompositions:

29 + 8656169 = 8656198
101 + 8656097 = 8656198
107 + 8656091 = 8656198
167 + 8656031 = 8656198
179 + 8656019 = 8656198
281 + 8655917 = 8656198
389 + 8655809 = 8656198
449 + 8655749 = 8656198

Showing the first eight; more decompositions exist.
