Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8786, here are decompositions:

3 + 8783 = 8786
7 + 8779 = 8786
67 + 8719 = 8786
73 + 8713 = 8786
79 + 8707 = 8786
97 + 8689 = 8786
109 + 8677 = 8786
139 + 8647 = 8786

Showing the first eight; more decompositions exist.
