Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717748, here are decompositions:
- 5 + 8717743 = 8717748
- 7 + 8717741 = 8717748
- 31 + 8717717 = 8717748
- 59 + 8717689 = 8717748
- 71 + 8717677 = 8717748
- 157 + 8717591 = 8717748
- 191 + 8717557 = 8717748
- 197 + 8717551 = 8717748
Showing the first eight; more decompositions exist.
