Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527424, here are decompositions:
- 11 + 31527413 = 31527424
- 17 + 31527407 = 31527424
- 101 + 31527323 = 31527424
- 107 + 31527317 = 31527424
- 113 + 31527311 = 31527424
- 191 + 31527233 = 31527424
- 233 + 31527191 = 31527424
- 251 + 31527173 = 31527424
Showing the first eight; more decompositions exist.
