Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18946, here are decompositions:

29 + 18917 = 18946
47 + 18899 = 18946
107 + 18839 = 18946
149 + 18797 = 18946
173 + 18773 = 18946
197 + 18749 = 18946
227 + 18719 = 18946
233 + 18713 = 18946

Showing the first eight; more decompositions exist.
