Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17018, here are decompositions:

7 + 17011 = 17018
31 + 16987 = 17018
37 + 16981 = 17018
97 + 16921 = 17018
139 + 16879 = 17018
271 + 16747 = 17018
277 + 16741 = 17018
367 + 16651 = 17018

Showing the first eight; more decompositions exist.
