Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189230, here are decompositions:

7 + 189223 = 189230
31 + 189199 = 189230
43 + 189187 = 189230
61 + 189169 = 189230
79 + 189151 = 189230
103 + 189127 = 189230
163 + 189067 = 189230
211 + 189019 = 189230

Showing the first eight; more decompositions exist.
