Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186684, here are decompositions:

5 + 186679 = 186684
13 + 186671 = 186684
31 + 186653 = 186684
37 + 186647 = 186684
83 + 186601 = 186684
97 + 186587 = 186684
101 + 186583 = 186684
103 + 186581 = 186684

Showing the first eight; more decompositions exist.
