Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16144, here are decompositions:
- 3 + 16141 = 16144
- 5 + 16139 = 16144
- 17 + 16127 = 16144
- 41 + 16103 = 16144
- 47 + 16097 = 16144
- 53 + 16091 = 16144
- 71 + 16073 = 16144
- 83 + 16061 = 16144
Showing the first eight; more decompositions exist.
