Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11800, here are decompositions:

11 + 11789 = 11800
17 + 11783 = 11800
23 + 11777 = 11800
83 + 11717 = 11800
101 + 11699 = 11800
167 + 11633 = 11800
179 + 11621 = 11800
251 + 11549 = 11800

Showing the first eight; more decompositions exist.
