Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16504, here are decompositions:

11 + 16493 = 16504
17 + 16487 = 16504
23 + 16481 = 16504
53 + 16451 = 16504
71 + 16433 = 16504
83 + 16421 = 16504
251 + 16253 = 16504
281 + 16223 = 16504

Showing the first eight; more decompositions exist.
