Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16500, here are decompositions:

7 + 16493 = 16500
13 + 16487 = 16500
19 + 16481 = 16500
23 + 16477 = 16500
47 + 16453 = 16500
53 + 16447 = 16500
67 + 16433 = 16500
73 + 16427 = 16500

Showing the first eight; more decompositions exist.
