Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40456, here are decompositions:
- 23 + 40433 = 40456
- 29 + 40427 = 40456
- 113 + 40343 = 40456
- 167 + 40289 = 40456
- 173 + 40283 = 40456
- 179 + 40277 = 40456
- 263 + 40193 = 40456
- 293 + 40163 = 40456
Showing the first eight; more decompositions exist.
