Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617854, here are decompositions:

17 + 8617837 = 8617854
31 + 8617823 = 8617854
67 + 8617787 = 8617854
101 + 8617753 = 8617854
151 + 8617703 = 8617854
173 + 8617681 = 8617854
227 + 8617627 = 8617854
293 + 8617561 = 8617854

Showing the first eight; more decompositions exist.
