Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173228, here are decompositions:
- 19 + 173209 = 173228
- 37 + 173191 = 173228
- 79 + 173149 = 173228
- 229 + 172999 = 173228
- 241 + 172987 = 173228
- 379 + 172849 = 173228
- 421 + 172807 = 173228
- 487 + 172741 = 173228
Showing the first eight; more decompositions exist.
