Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189418, here are decompositions:

11 + 189407 = 189418
17 + 189401 = 189418
29 + 189389 = 189418
41 + 189377 = 189418
71 + 189347 = 189418
107 + 189311 = 189418
167 + 189251 = 189418
179 + 189239 = 189418

Showing the first eight; more decompositions exist.
