Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16518, here are decompositions:

31 + 16487 = 16518
37 + 16481 = 16518
41 + 16477 = 16518
67 + 16451 = 16518
71 + 16447 = 16518
97 + 16421 = 16518
101 + 16417 = 16518
107 + 16411 = 16518

Showing the first eight; more decompositions exist.
