Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8146, here are decompositions:
- 23 + 8123 = 8146
- 29 + 8117 = 8146
- 53 + 8093 = 8146
- 59 + 8087 = 8146
- 107 + 8039 = 8146
- 137 + 8009 = 8146
- 197 + 7949 = 8146
- 227 + 7919 = 8146
Showing the first eight; more decompositions exist.
