Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143726, here are decompositions:
- 7 + 143719 = 143726
- 73 + 143653 = 143726
- 97 + 143629 = 143726
- 109 + 143617 = 143726
- 157 + 143569 = 143726
- 199 + 143527 = 143726
- 223 + 143503 = 143726
- 283 + 143443 = 143726
Showing the first eight; more decompositions exist.
