Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167220, here are decompositions:
- 7 + 167213 = 167220
- 23 + 167197 = 167220
- 29 + 167191 = 167220
- 43 + 167177 = 167220
- 47 + 167173 = 167220
- 61 + 167159 = 167220
- 71 + 167149 = 167220
- 101 + 167119 = 167220
Showing the first eight; more decompositions exist.
