Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19166, here are decompositions:

3 + 19163 = 19166
79 + 19087 = 19166
97 + 19069 = 19166
157 + 19009 = 19166
193 + 18973 = 19166
307 + 18859 = 19166
373 + 18793 = 19166
379 + 18787 = 19166

Showing the first eight; more decompositions exist.
