Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718804, here are decompositions:

5 + 8718799 = 8718804
7 + 8718797 = 8718804
11 + 8718793 = 8718804
47 + 8718757 = 8718804
67 + 8718737 = 8718804
71 + 8718733 = 8718804
131 + 8718673 = 8718804
223 + 8718581 = 8718804

Showing the first eight; more decompositions exist.
