Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655876, here are decompositions:

7 + 8655869 = 8655876
17 + 8655859 = 8655876
67 + 8655809 = 8655876
107 + 8655769 = 8655876
127 + 8655749 = 8655876
137 + 8655739 = 8655876
157 + 8655719 = 8655876
197 + 8655679 = 8655876

Showing the first eight; more decompositions exist.
