Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173180, here are decompositions:
- 3 + 173177 = 173180
- 31 + 173149 = 173180
- 43 + 173137 = 173180
- 127 + 173053 = 173180
- 157 + 173023 = 173180
- 181 + 172999 = 173180
- 193 + 172987 = 173180
- 199 + 172981 = 173180
Showing the first eight; more decompositions exist.
