Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10808, here are decompositions:

19 + 10789 = 10808
37 + 10771 = 10808
79 + 10729 = 10808
97 + 10711 = 10808
151 + 10657 = 10808
157 + 10651 = 10808
181 + 10627 = 10808
211 + 10597 = 10808

Showing the first eight; more decompositions exist.
