Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186784, here are decompositions:

11 + 186773 = 186784
23 + 186761 = 186784
41 + 186743 = 186784
83 + 186701 = 186784
113 + 186671 = 186784
131 + 186653 = 186784
137 + 186647 = 186784
197 + 186587 = 186784

Showing the first eight; more decompositions exist.
