Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16240, here are decompositions:
- 11 + 16229 = 16240
- 17 + 16223 = 16240
- 23 + 16217 = 16240
- 47 + 16193 = 16240
- 53 + 16187 = 16240
- 101 + 16139 = 16240
- 113 + 16127 = 16240
- 137 + 16103 = 16240
Showing the first eight; more decompositions exist.
