Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 106668, here are decompositions:

5 + 106663 = 106668
7 + 106661 = 106668
11 + 106657 = 106668
19 + 106649 = 106668
31 + 106637 = 106668
41 + 106627 = 106668
47 + 106621 = 106668
127 + 106541 = 106668

Showing the first eight; more decompositions exist.
