Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12170, here are decompositions:
- 7 + 12163 = 12170
- 13 + 12157 = 12170
- 61 + 12109 = 12170
- 73 + 12097 = 12170
- 97 + 12073 = 12170
- 127 + 12043 = 12170
- 163 + 12007 = 12170
- 199 + 11971 = 12170
Showing the first eight; more decompositions exist.
