Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18716, here are decompositions:

3 + 18713 = 18716
37 + 18679 = 18716
79 + 18637 = 18716
163 + 18553 = 18716
193 + 18523 = 18716
199 + 18517 = 18716
223 + 18493 = 18716
277 + 18439 = 18716

Showing the first eight; more decompositions exist.
