Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16488, here are decompositions:
- 7 + 16481 = 16488
- 11 + 16477 = 16488
- 37 + 16451 = 16488
- 41 + 16447 = 16488
- 61 + 16427 = 16488
- 67 + 16421 = 16488
- 71 + 16417 = 16488
- 107 + 16381 = 16488
Showing the first eight; more decompositions exist.
