Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29018, here are decompositions:

97 + 28921 = 29018
109 + 28909 = 29018
139 + 28879 = 29018
151 + 28867 = 29018
181 + 28837 = 29018
211 + 28807 = 29018
229 + 28789 = 29018
307 + 28711 = 29018

Showing the first eight; more decompositions exist.
