Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655828, here are decompositions:

19 + 8655809 = 8655828
59 + 8655769 = 8655828
67 + 8655761 = 8655828
79 + 8655749 = 8655828
89 + 8655739 = 8655828
107 + 8655721 = 8655828
109 + 8655719 = 8655828
127 + 8655701 = 8655828

Showing the first eight; more decompositions exist.
