Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16486, here are decompositions:

5 + 16481 = 16486
53 + 16433 = 16486
59 + 16427 = 16486
137 + 16349 = 16486
167 + 16319 = 16486
233 + 16253 = 16486
257 + 16229 = 16486
263 + 16223 = 16486

Showing the first eight; more decompositions exist.
