Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8406, here are decompositions:
- 17 + 8389 = 8406
- 19 + 8387 = 8406
- 29 + 8377 = 8406
- 37 + 8369 = 8406
- 43 + 8363 = 8406
- 53 + 8353 = 8406
- 89 + 8317 = 8406
- 109 + 8297 = 8406
Showing the first eight; more decompositions exist.
