Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17240, here are decompositions:

31 + 17209 = 17240
37 + 17203 = 17240
73 + 17167 = 17240
103 + 17137 = 17240
163 + 17077 = 17240
193 + 17047 = 17240
199 + 17041 = 17240
211 + 17029 = 17240

Showing the first eight; more decompositions exist.
