Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18194, here are decompositions:

3 + 18191 = 18194
13 + 18181 = 18194
61 + 18133 = 18194
67 + 18127 = 18194
73 + 18121 = 18194
97 + 18097 = 18194
151 + 18043 = 18194
181 + 18013 = 18194

Showing the first eight; more decompositions exist.
