Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173972, here are decompositions:
- 3 + 173969 = 173972
- 193 + 173779 = 173972
- 199 + 173773 = 173972
- 229 + 173743 = 173972
- 313 + 173659 = 173972
- 373 + 173599 = 173972
- 433 + 173539 = 173972
- 499 + 173473 = 173972
Showing the first eight; more decompositions exist.
