Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18496, here are decompositions:

3 + 18493 = 18496
53 + 18443 = 18496
83 + 18413 = 18496
167 + 18329 = 18496
227 + 18269 = 18496
239 + 18257 = 18496
263 + 18233 = 18496
347 + 18149 = 18496

Showing the first eight; more decompositions exist.
