Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163772, here are decompositions:
- 19 + 163753 = 163772
- 31 + 163741 = 163772
- 43 + 163729 = 163772
- 139 + 163633 = 163772
- 151 + 163621 = 163772
- 199 + 163573 = 163772
- 211 + 163561 = 163772
- 229 + 163543 = 163772
Showing the first eight; more decompositions exist.
