Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11156, here are decompositions:

7 + 11149 = 11156
37 + 11119 = 11156
43 + 11113 = 11156
73 + 11083 = 11156
97 + 11059 = 11156
109 + 11047 = 11156
163 + 10993 = 11156
199 + 10957 = 11156

Showing the first eight; more decompositions exist.
