Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28318, here are decompositions:

11 + 28307 = 28318
29 + 28289 = 28318
41 + 28277 = 28318
89 + 28229 = 28318
107 + 28211 = 28318
137 + 28181 = 28318
167 + 28151 = 28318
317 + 28001 = 28318

Showing the first eight; more decompositions exist.
