Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175644, here are decompositions:
- 11 + 175633 = 175644
- 13 + 175631 = 175644
- 23 + 175621 = 175644
- 43 + 175601 = 175644
- 71 + 175573 = 175644
- 101 + 175543 = 175644
- 151 + 175493 = 175644
- 163 + 175481 = 175644
Showing the first eight; more decompositions exist.
