Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718808, here are decompositions:

5 + 8718803 = 8718808
11 + 8718797 = 8718808
29 + 8718779 = 8718808
71 + 8718737 = 8718808
227 + 8718581 = 8718808
269 + 8718539 = 8718808
317 + 8718491 = 8718808
347 + 8718461 = 8718808

Showing the first eight; more decompositions exist.
