Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189436, here are decompositions:

3 + 189433 = 189436
29 + 189407 = 189436
47 + 189389 = 189436
59 + 189377 = 189436
83 + 189353 = 189436
89 + 189347 = 189436
179 + 189257 = 189436
197 + 189239 = 189436

Showing the first eight; more decompositions exist.
