Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16140, here are decompositions:
- 13 + 16127 = 16140
- 29 + 16111 = 16140
- 37 + 16103 = 16140
- 43 + 16097 = 16140
- 53 + 16087 = 16140
- 67 + 16073 = 16140
- 71 + 16069 = 16140
- 73 + 16067 = 16140
Showing the first eight; more decompositions exist.
