Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173432, here are decompositions:
- 3 + 173429 = 173432
- 73 + 173359 = 173432
- 139 + 173293 = 173432
- 223 + 173209 = 173432
- 241 + 173191 = 173432
- 283 + 173149 = 173432
- 373 + 173059 = 173432
- 379 + 173053 = 173432
Showing the first eight; more decompositions exist.
