Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707866, here are decompositions:

5 + 8707861 = 8707866
23 + 8707843 = 8707866
29 + 8707837 = 8707866
73 + 8707793 = 8707866
103 + 8707763 = 8707866
113 + 8707753 = 8707866
179 + 8707687 = 8707866
197 + 8707669 = 8707866

Showing the first eight; more decompositions exist.
