Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527456, here are decompositions:
- 43 + 31527413 = 31527456
- 67 + 31527389 = 31527456
- 113 + 31527343 = 31527456
- 139 + 31527317 = 31527456
- 179 + 31527277 = 31527456
- 223 + 31527233 = 31527456
- 263 + 31527193 = 31527456
- 283 + 31527173 = 31527456
Showing the first eight; more decompositions exist.
