Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18726, here are decompositions:

7 + 18719 = 18726
13 + 18713 = 18726
47 + 18679 = 18726
89 + 18637 = 18726
109 + 18617 = 18726
139 + 18587 = 18726
173 + 18553 = 18726
223 + 18503 = 18726

Showing the first eight; more decompositions exist.
