Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72874, here are decompositions:
- 3 + 72871 = 72874
- 5 + 72869 = 72874
- 107 + 72767 = 72874
- 167 + 72707 = 72874
- 173 + 72701 = 72874
- 227 + 72647 = 72874
- 251 + 72623 = 72874
- 257 + 72617 = 72874
Showing the first eight; more decompositions exist.
