Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17518, here are decompositions:

29 + 17489 = 17518
41 + 17477 = 17518
47 + 17471 = 17518
101 + 17417 = 17518
131 + 17387 = 17518
167 + 17351 = 17518
191 + 17327 = 17518
197 + 17321 = 17518

Showing the first eight; more decompositions exist.
