Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717786, here are decompositions:

3 + 8717783 = 8717786
13 + 8717773 = 8717786
19 + 8717767 = 8717786
37 + 8717749 = 8717786
43 + 8717743 = 8717786
97 + 8717689 = 8717786
109 + 8717677 = 8717786
163 + 8717623 = 8717786

Showing the first eight; more decompositions exist.
