Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699888, here are decompositions:

31 + 8699857 = 8699888
37 + 8699851 = 8699888
61 + 8699827 = 8699888
157 + 8699731 = 8699888
229 + 8699659 = 8699888
277 + 8699611 = 8699888
331 + 8699557 = 8699888
349 + 8699539 = 8699888

Showing the first eight; more decompositions exist.
