Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11172, here are decompositions:

11 + 11161 = 11172
13 + 11159 = 11172
23 + 11149 = 11172
41 + 11131 = 11172
53 + 11119 = 11172
59 + 11113 = 11172
79 + 11093 = 11172
89 + 11083 = 11172

Showing the first eight; more decompositions exist.
