Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12146, here are decompositions:
- 3 + 12143 = 12146
- 37 + 12109 = 12146
- 73 + 12073 = 12146
- 97 + 12049 = 12146
- 103 + 12043 = 12146
- 109 + 12037 = 12146
- 139 + 12007 = 12146
- 193 + 11953 = 12146
Showing the first eight; more decompositions exist.
