Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16146, here are decompositions:
- 5 + 16141 = 16146
- 7 + 16139 = 16146
- 19 + 16127 = 16146
- 43 + 16103 = 16146
- 59 + 16087 = 16146
- 73 + 16073 = 16146
- 79 + 16067 = 16146
- 83 + 16063 = 16146
Showing the first eight; more decompositions exist.
