Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737680, here are decompositions:
- 11 + 8737669 = 8737680
- 13 + 8737667 = 8737680
- 23 + 8737657 = 8737680
- 53 + 8737627 = 8737680
- 89 + 8737591 = 8737680
- 97 + 8737583 = 8737680
- 103 + 8737577 = 8737680
- 109 + 8737571 = 8737680
Showing the first eight; more decompositions exist.
