Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78432, here are decompositions:
- 5 + 78427 = 78432
- 31 + 78401 = 78432
- 131 + 78301 = 78432
- 149 + 78283 = 78432
- 173 + 78259 = 78432
- 191 + 78241 = 78432
- 199 + 78233 = 78432
- 229 + 78203 = 78432
Showing the first eight; more decompositions exist.
