Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18864, here are decompositions:

5 + 18859 = 18864
61 + 18803 = 18864
67 + 18797 = 18864
71 + 18793 = 18864
107 + 18757 = 18864
151 + 18713 = 18864
163 + 18701 = 18864
173 + 18691 = 18864

Showing the first eight; more decompositions exist.
