Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189396, here are decompositions:

5 + 189391 = 189396
7 + 189389 = 189396
19 + 189377 = 189396
43 + 189353 = 189396
47 + 189349 = 189396
59 + 189337 = 189396
89 + 189307 = 189396
139 + 189257 = 189396

Showing the first eight; more decompositions exist.
