Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6906, here are decompositions:

7 + 6899 = 6906
23 + 6883 = 6906
37 + 6869 = 6906
43 + 6863 = 6906
73 + 6833 = 6906
79 + 6827 = 6906
83 + 6823 = 6906
103 + 6803 = 6906

Showing the first eight; more decompositions exist.
