Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18704, here are decompositions:

3 + 18701 = 18704
13 + 18691 = 18704
43 + 18661 = 18704
67 + 18637 = 18704
151 + 18553 = 18704
163 + 18541 = 18704
181 + 18523 = 18704
211 + 18493 = 18704

Showing the first eight; more decompositions exist.
