Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23018, here are decompositions:

7 + 23011 = 23018
97 + 22921 = 23018
157 + 22861 = 23018
211 + 22807 = 23018
241 + 22777 = 23018
277 + 22741 = 23018
349 + 22669 = 23018
367 + 22651 = 23018

Showing the first eight; more decompositions exist.
