Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11120, here are decompositions:

3 + 11117 = 11120
7 + 11113 = 11120
37 + 11083 = 11120
61 + 11059 = 11120
73 + 11047 = 11120
127 + 10993 = 11120
163 + 10957 = 11120
181 + 10939 = 11120

Showing the first eight; more decompositions exist.
