Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718910, here are decompositions:

3 + 8718907 = 8718910
23 + 8718887 = 8718910
29 + 8718881 = 8718910
41 + 8718869 = 8718910
59 + 8718851 = 8718910
71 + 8718839 = 8718910
107 + 8718803 = 8718910
113 + 8718797 = 8718910

Showing the first eight; more decompositions exist.
