Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11678, here are decompositions:

61 + 11617 = 11678
127 + 11551 = 11678
151 + 11527 = 11678
181 + 11497 = 11678
211 + 11467 = 11678
241 + 11437 = 11678
349 + 11329 = 11678
367 + 11311 = 11678

Showing the first eight; more decompositions exist.
