Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72898, here are decompositions:
- 5 + 72893 = 72898
- 29 + 72869 = 72898
- 101 + 72797 = 72898
- 131 + 72767 = 72898
- 179 + 72719 = 72898
- 191 + 72707 = 72898
- 197 + 72701 = 72898
- 227 + 72671 = 72898
Showing the first eight; more decompositions exist.
