Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31366, here are decompositions:
- 29 + 31337 = 31366
- 47 + 31319 = 31366
- 59 + 31307 = 31366
- 89 + 31277 = 31366
- 107 + 31259 = 31366
- 113 + 31253 = 31366
- 173 + 31193 = 31366
- 227 + 31139 = 31366
Showing the first eight; more decompositions exist.
