Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737686, here are decompositions:
- 17 + 8737669 = 8737686
- 19 + 8737667 = 8737686
- 29 + 8737657 = 8737686
- 59 + 8737627 = 8737686
- 103 + 8737583 = 8737686
- 109 + 8737577 = 8737686
- 157 + 8737529 = 8737686
- 163 + 8737523 = 8737686
Showing the first eight; more decompositions exist.
