Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86786, here are decompositions:

3 + 86783 = 86786
19 + 86767 = 86786
43 + 86743 = 86786
67 + 86719 = 86786
97 + 86689 = 86786
109 + 86677 = 86786
157 + 86629 = 86786
199 + 86587 = 86786

Showing the first eight; more decompositions exist.
