Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655930, here are decompositions:

7 + 8655923 = 8655930
11 + 8655919 = 8655930
13 + 8655917 = 8655930
29 + 8655901 = 8655930
47 + 8655883 = 8655930
53 + 8655877 = 8655930
61 + 8655869 = 8655930
71 + 8655859 = 8655930

Showing the first eight; more decompositions exist.
