Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173644, here are decompositions:
- 71 + 173573 = 173644
- 83 + 173561 = 173644
- 101 + 173543 = 173644
- 113 + 173531 = 173644
- 347 + 173297 = 173644
- 353 + 173291 = 173644
- 461 + 173183 = 173644
- 467 + 173177 = 173644
Showing the first eight; more decompositions exist.
