Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175720, here are decompositions:
- 11 + 175709 = 175720
- 29 + 175691 = 175720
- 47 + 175673 = 175720
- 71 + 175649 = 175720
- 89 + 175631 = 175720
- 197 + 175523 = 175720
- 227 + 175493 = 175720
- 239 + 175481 = 175720
Showing the first eight; more decompositions exist.
