Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188150, here are decompositions:

3 + 188147 = 188150
7 + 188143 = 188150
13 + 188137 = 188150
43 + 188107 = 188150
139 + 188011 = 188150
163 + 187987 = 188150
199 + 187951 = 188150
223 + 187927 = 188150

Showing the first eight; more decompositions exist.
