Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698, here are decompositions:
- 5 + 8693 = 8698
- 17 + 8681 = 8698
- 29 + 8669 = 8698
- 71 + 8627 = 8698
- 89 + 8609 = 8698
- 101 + 8597 = 8698
- 197 + 8501 = 8698
- 251 + 8447 = 8698
Showing the first eight; more decompositions exist.
