Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655906, here are decompositions:

5 + 8655901 = 8655906
23 + 8655883 = 8655906
29 + 8655877 = 8655906
37 + 8655869 = 8655906
47 + 8655859 = 8655906
97 + 8655809 = 8655906
137 + 8655769 = 8655906
157 + 8655749 = 8655906

Showing the first eight; more decompositions exist.
