Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665956, here are decompositions:

7 + 8665949 = 8665956
17 + 8665939 = 8665956
23 + 8665933 = 8665956
43 + 8665913 = 8665956
59 + 8665897 = 8665956
67 + 8665889 = 8665956
83 + 8665873 = 8665956
107 + 8665849 = 8665956

Showing the first eight; more decompositions exist.
