Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189940, here are decompositions:

11 + 189929 = 189940
53 + 189887 = 189940
59 + 189881 = 189940
89 + 189851 = 189940
173 + 189767 = 189940
197 + 189743 = 189940
227 + 189713 = 189940
239 + 189701 = 189940

Showing the first eight; more decompositions exist.
