Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86822, here are decompositions:

79 + 86743 = 86822
103 + 86719 = 86822
193 + 86629 = 86822
223 + 86599 = 86822
283 + 86539 = 86822
313 + 86509 = 86822
331 + 86491 = 86822
409 + 86413 = 86822

Showing the first eight; more decompositions exist.
