Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86738, here are decompositions:

19 + 86719 = 86738
61 + 86677 = 86738
109 + 86629 = 86738
139 + 86599 = 86738
151 + 86587 = 86738
199 + 86539 = 86738
229 + 86509 = 86738
271 + 86467 = 86738

Showing the first eight; more decompositions exist.
