Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17140, here are decompositions:

3 + 17137 = 17140
17 + 17123 = 17140
23 + 17117 = 17140
41 + 17099 = 17140
47 + 17093 = 17140
107 + 17033 = 17140
113 + 17027 = 17140
197 + 16943 = 17140

Showing the first eight; more decompositions exist.
