Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717884, here are decompositions:

3 + 8717881 = 8717884
11 + 8717873 = 8717884
17 + 8717867 = 8717884
23 + 8717861 = 8717884
41 + 8717843 = 8717884
101 + 8717783 = 8717884
137 + 8717747 = 8717884
167 + 8717717 = 8717884

Showing the first eight; more decompositions exist.
