Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16510, here are decompositions:

17 + 16493 = 16510
23 + 16487 = 16510
29 + 16481 = 16510
59 + 16451 = 16510
83 + 16427 = 16510
89 + 16421 = 16510
149 + 16361 = 16510
191 + 16319 = 16510

Showing the first eight; more decompositions exist.
