Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18678, here are decompositions:

7 + 18671 = 18678
17 + 18661 = 18678
41 + 18637 = 18678
61 + 18617 = 18678
137 + 18541 = 18678
139 + 18539 = 18678
157 + 18521 = 18678
197 + 18481 = 18678

Showing the first eight; more decompositions exist.
