Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11906, here are decompositions:

3 + 11903 = 11906
19 + 11887 = 11906
43 + 11863 = 11906
67 + 11839 = 11906
73 + 11833 = 11906
79 + 11827 = 11906
127 + 11779 = 11906
163 + 11743 = 11906

Showing the first eight; more decompositions exist.
