Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660856, here are decompositions:

37 + 8660819 = 8660856
59 + 8660797 = 8660856
89 + 8660767 = 8660856
103 + 8660753 = 8660856
109 + 8660747 = 8660856
157 + 8660699 = 8660856
163 + 8660693 = 8660856
167 + 8660689 = 8660856

Showing the first eight; more decompositions exist.
