Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12808, here are decompositions:

17 + 12791 = 12808
137 + 12671 = 12808
149 + 12659 = 12808
167 + 12641 = 12808
197 + 12611 = 12808
239 + 12569 = 12808
269 + 12539 = 12808
281 + 12527 = 12808

Showing the first eight; more decompositions exist.
