Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617860, here are decompositions:

23 + 8617837 = 8617860
37 + 8617823 = 8617860
61 + 8617799 = 8617860
73 + 8617787 = 8617860
107 + 8617753 = 8617860
157 + 8617703 = 8617860
179 + 8617681 = 8617860
233 + 8617627 = 8617860

Showing the first eight; more decompositions exist.
