Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16512, here are decompositions:

19 + 16493 = 16512
31 + 16481 = 16512
59 + 16453 = 16512
61 + 16451 = 16512
79 + 16433 = 16512
101 + 16411 = 16512
131 + 16381 = 16512
149 + 16363 = 16512

Showing the first eight; more decompositions exist.
