Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86780, here are decompositions:

13 + 86767 = 86780
37 + 86743 = 86780
61 + 86719 = 86780
103 + 86677 = 86780
151 + 86629 = 86780
181 + 86599 = 86780
193 + 86587 = 86780
241 + 86539 = 86780

Showing the first eight; more decompositions exist.
