Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8018, here are decompositions:

7 + 8011 = 8018
67 + 7951 = 8018
139 + 7879 = 8018
151 + 7867 = 8018
229 + 7789 = 8018
277 + 7741 = 8018
331 + 7687 = 8018
337 + 7681 = 8018

Showing the first eight; more decompositions exist.
