Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654856, here are decompositions:

17 + 8654839 = 8654856
19 + 8654837 = 8654856
47 + 8654809 = 8654856
53 + 8654803 = 8654856
83 + 8654773 = 8654856
97 + 8654759 = 8654856
103 + 8654753 = 8654856
107 + 8654749 = 8654856

Showing the first eight; more decompositions exist.
