Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31364, here are decompositions:
- 7 + 31357 = 31364
- 31 + 31333 = 31364
- 37 + 31327 = 31364
- 43 + 31321 = 31364
- 97 + 31267 = 31364
- 127 + 31237 = 31364
- 181 + 31183 = 31364
- 211 + 31153 = 31364
Showing the first eight; more decompositions exist.
