Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189210, here are decompositions:

11 + 189199 = 189210
23 + 189187 = 189210
41 + 189169 = 189210
59 + 189151 = 189210
61 + 189149 = 189210
71 + 189139 = 189210
83 + 189127 = 189210
149 + 189061 = 189210

Showing the first eight; more decompositions exist.
