Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71680, here are decompositions:
- 17 + 71663 = 71680
- 47 + 71633 = 71680
- 83 + 71597 = 71680
- 131 + 71549 = 71680
- 197 + 71483 = 71680
- 227 + 71453 = 71680
- 251 + 71429 = 71680
- 269 + 71411 = 71680
Showing the first eight; more decompositions exist.
