Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11148, here are decompositions:

17 + 11131 = 11148
29 + 11119 = 11148
31 + 11117 = 11148
61 + 11087 = 11148
79 + 11069 = 11148
89 + 11059 = 11148
101 + 11047 = 11148
191 + 10957 = 11148

Showing the first eight; more decompositions exist.
