Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18892, here are decompositions:

23 + 18869 = 18892
53 + 18839 = 18892
89 + 18803 = 18892
149 + 18743 = 18892
173 + 18719 = 18892
179 + 18713 = 18892
191 + 18701 = 18892
353 + 18539 = 18892

Showing the first eight; more decompositions exist.
