Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86636, here are decompositions:

7 + 86629 = 86636
37 + 86599 = 86636
97 + 86539 = 86636
103 + 86533 = 86636
127 + 86509 = 86636
223 + 86413 = 86636
283 + 86353 = 86636
313 + 86323 = 86636

Showing the first eight; more decompositions exist.
