Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13678, here are decompositions:

29 + 13649 = 13678
59 + 13619 = 13678
101 + 13577 = 13678
179 + 13499 = 13678
191 + 13487 = 13678
227 + 13451 = 13678
257 + 13421 = 13678
281 + 13397 = 13678

Showing the first eight; more decompositions exist.
