Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189406, here are decompositions:

5 + 189401 = 189406
17 + 189389 = 189406
29 + 189377 = 189406
53 + 189353 = 189406
59 + 189347 = 189406
149 + 189257 = 189406
167 + 189239 = 189406
257 + 189149 = 189406

Showing the first eight; more decompositions exist.
