Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40432, here are decompositions:
- 3 + 40429 = 40432
- 5 + 40427 = 40432
- 71 + 40361 = 40432
- 89 + 40343 = 40432
- 149 + 40283 = 40432
- 179 + 40253 = 40432
- 191 + 40241 = 40432
- 239 + 40193 = 40432
Showing the first eight; more decompositions exist.
