Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27686, here are decompositions:

13 + 27673 = 27686
103 + 27583 = 27686
157 + 27529 = 27686
199 + 27487 = 27686
229 + 27457 = 27686
277 + 27409 = 27686
349 + 27337 = 27686
409 + 27277 = 27686

Showing the first eight; more decompositions exist.
