Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188146, here are decompositions:

3 + 188143 = 188146
173 + 187973 = 188146
239 + 187907 = 188146
263 + 187883 = 188146
269 + 187877 = 188146
353 + 187793 = 188146
359 + 187787 = 188146
383 + 187763 = 188146

Showing the first eight; more decompositions exist.
