Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31418, here are decompositions:
- 31 + 31387 = 31418
- 61 + 31357 = 31418
- 97 + 31321 = 31418
- 151 + 31267 = 31418
- 181 + 31237 = 31418
- 199 + 31219 = 31418
- 229 + 31189 = 31418
- 241 + 31177 = 31418
Showing the first eight; more decompositions exist.
