Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8486, here are decompositions:
- 19 + 8467 = 8486
- 43 + 8443 = 8486
- 67 + 8419 = 8486
- 97 + 8389 = 8486
- 109 + 8377 = 8486
- 157 + 8329 = 8486
- 193 + 8293 = 8486
- 199 + 8287 = 8486
Showing the first eight; more decompositions exist.
