Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189646, here are decompositions:

3 + 189643 = 189646
29 + 189617 = 189646
47 + 189599 = 189646
53 + 189593 = 189646
137 + 189509 = 189646
167 + 189479 = 189646
173 + 189473 = 189646
179 + 189467 = 189646

Showing the first eight; more decompositions exist.
