Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47542, here are decompositions:
- 29 + 47513 = 47542
- 41 + 47501 = 47542
- 83 + 47459 = 47542
- 101 + 47441 = 47542
- 179 + 47363 = 47542
- 191 + 47351 = 47542
- 233 + 47309 = 47542
- 239 + 47303 = 47542
Showing the first eight; more decompositions exist.
