Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23686, here are decompositions:

17 + 23669 = 23686
23 + 23663 = 23686
53 + 23633 = 23686
59 + 23627 = 23686
83 + 23603 = 23686
137 + 23549 = 23686
149 + 23537 = 23686
227 + 23459 = 23686

Showing the first eight; more decompositions exist.
