Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189172, here are decompositions:

3 + 189169 = 189172
23 + 189149 = 189172
131 + 189041 = 189172
173 + 188999 = 189172
233 + 188939 = 189172
239 + 188933 = 189172
281 + 188891 = 189172
311 + 188861 = 189172

Showing the first eight; more decompositions exist.
