Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729968, here are decompositions:
- 29 + 8729939 = 8729968
- 101 + 8729867 = 8729968
- 131 + 8729837 = 8729968
- 167 + 8729801 = 8729968
- 239 + 8729729 = 8729968
- 251 + 8729717 = 8729968
- 257 + 8729711 = 8729968
- 347 + 8729621 = 8729968
Showing the first eight; more decompositions exist.
