Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724, here are decompositions:
- 5 + 8719 = 8724
- 11 + 8713 = 8724
- 17 + 8707 = 8724
- 31 + 8693 = 8724
- 43 + 8681 = 8724
- 47 + 8677 = 8724
- 61 + 8663 = 8724
- 83 + 8641 = 8724
Showing the first eight; more decompositions exist.
