Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71656, here are decompositions:
- 23 + 71633 = 71656
- 59 + 71597 = 71656
- 107 + 71549 = 71656
- 173 + 71483 = 71656
- 227 + 71429 = 71656
- 257 + 71399 = 71656
- 269 + 71387 = 71656
- 293 + 71363 = 71656
Showing the first eight; more decompositions exist.
