Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11166, here are decompositions:

5 + 11161 = 11166
7 + 11159 = 11166
17 + 11149 = 11166
47 + 11119 = 11166
53 + 11113 = 11166
73 + 11093 = 11166
79 + 11087 = 11166
83 + 11083 = 11166

Showing the first eight; more decompositions exist.
