Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16906, here are decompositions:

3 + 16903 = 16906
5 + 16901 = 16906
17 + 16889 = 16906
23 + 16883 = 16906
83 + 16823 = 16906
233 + 16673 = 16906
257 + 16649 = 16906
353 + 16553 = 16906

Showing the first eight; more decompositions exist.
