Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26906, here are decompositions:

3 + 26903 = 26906
13 + 26893 = 26906
43 + 26863 = 26906
67 + 26839 = 26906
73 + 26833 = 26906
193 + 26713 = 26906
223 + 26683 = 26906
349 + 26557 = 26906

Showing the first eight; more decompositions exist.
