Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189208, here are decompositions:

59 + 189149 = 189208
167 + 189041 = 189208
191 + 189017 = 189208
197 + 189011 = 189208
251 + 188957 = 189208
269 + 188939 = 189208
281 + 188927 = 189208
317 + 188891 = 189208

Showing the first eight; more decompositions exist.
