Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27668, here are decompositions:

37 + 27631 = 27668
127 + 27541 = 27668
139 + 27529 = 27668
181 + 27487 = 27668
211 + 27457 = 27668
241 + 27427 = 27668
271 + 27397 = 27668
307 + 27361 = 27668

Showing the first eight; more decompositions exist.
