Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47432, here are decompositions:
- 13 + 47419 = 47432
- 43 + 47389 = 47432
- 79 + 47353 = 47432
- 139 + 47293 = 47432
- 163 + 47269 = 47432
- 181 + 47251 = 47432
- 211 + 47221 = 47432
- 271 + 47161 = 47432
Showing the first eight; more decompositions exist.
