Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655888, here are decompositions:

5 + 8655883 = 8655888
11 + 8655877 = 8655888
19 + 8655869 = 8655888
29 + 8655859 = 8655888
47 + 8655841 = 8655888
79 + 8655809 = 8655888
127 + 8655761 = 8655888
139 + 8655749 = 8655888

Showing the first eight; more decompositions exist.
