Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47458, here are decompositions:
- 17 + 47441 = 47458
- 41 + 47417 = 47458
- 71 + 47387 = 47458
- 107 + 47351 = 47458
- 149 + 47309 = 47458
- 179 + 47279 = 47458
- 251 + 47207 = 47458
- 269 + 47189 = 47458
Showing the first eight; more decompositions exist.
