Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 106686, here are decompositions:

5 + 106681 = 106686
17 + 106669 = 106686
23 + 106663 = 106686
29 + 106657 = 106686
37 + 106649 = 106686
59 + 106627 = 106686
67 + 106619 = 106686
149 + 106537 = 106686

Showing the first eight; more decompositions exist.
