Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17118, here are decompositions:

11 + 17107 = 17118
19 + 17099 = 17118
41 + 17077 = 17118
71 + 17047 = 17118
89 + 17029 = 17118
97 + 17021 = 17118
107 + 17011 = 17118
131 + 16987 = 17118

Showing the first eight; more decompositions exist.
