Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636, here are decompositions:
- 7 + 8629 = 8636
- 13 + 8623 = 8636
- 37 + 8599 = 8636
- 73 + 8563 = 8636
- 97 + 8539 = 8636
- 109 + 8527 = 8636
- 193 + 8443 = 8636
- 283 + 8353 = 8636
Showing the first eight; more decompositions exist.
