Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635880, here are decompositions:

13 + 8635867 = 8635880
31 + 8635849 = 8635880
103 + 8635777 = 8635880
151 + 8635729 = 8635880
157 + 8635723 = 8635880
163 + 8635717 = 8635880
181 + 8635699 = 8635880
193 + 8635687 = 8635880

Showing the first eight; more decompositions exist.
