Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8426, here are decompositions:
- 3 + 8423 = 8426
- 7 + 8419 = 8426
- 37 + 8389 = 8426
- 73 + 8353 = 8426
- 97 + 8329 = 8426
- 109 + 8317 = 8426
- 139 + 8287 = 8426
- 157 + 8269 = 8426
Showing the first eight; more decompositions exist.
