Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11000, here are decompositions:

7 + 10993 = 11000
13 + 10987 = 11000
43 + 10957 = 11000
61 + 10939 = 11000
97 + 10903 = 11000
109 + 10891 = 11000
139 + 10861 = 11000
163 + 10837 = 11000

Showing the first eight; more decompositions exist.
