Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699880, here are decompositions:

23 + 8699857 = 8699880
29 + 8699851 = 8699880
53 + 8699827 = 8699880
67 + 8699813 = 8699880
73 + 8699807 = 8699880
109 + 8699771 = 8699880
127 + 8699753 = 8699880
149 + 8699731 = 8699880

Showing the first eight; more decompositions exist.
