Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31376, here are decompositions:
- 19 + 31357 = 31376
- 43 + 31333 = 31376
- 109 + 31267 = 31376
- 127 + 31249 = 31376
- 139 + 31237 = 31376
- 157 + 31219 = 31376
- 193 + 31183 = 31376
- 199 + 31177 = 31376
Showing the first eight; more decompositions exist.
