Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186940, here are decompositions:

23 + 186917 = 186940
71 + 186869 = 186940
167 + 186773 = 186940
179 + 186761 = 186940
197 + 186743 = 186940
233 + 186707 = 186940
239 + 186701 = 186940
251 + 186689 = 186940

Showing the first eight; more decompositions exist.
