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.
