Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186844, here are decompositions:

3 + 186841 = 186844
71 + 186773 = 186844
83 + 186761 = 186844
101 + 186743 = 186844
137 + 186707 = 186844
173 + 186671 = 186844
191 + 186653 = 186844
197 + 186647 = 186844

Showing the first eight; more decompositions exist.
