Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189946, here are decompositions:

17 + 189929 = 189946
59 + 189887 = 189946
149 + 189797 = 189946
179 + 189767 = 189946
233 + 189713 = 189946
293 + 189653 = 189946
347 + 189599 = 189946
353 + 189593 = 189946

Showing the first eight; more decompositions exist.
