Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31342, here are decompositions:
- 5 + 31337 = 31342
- 23 + 31319 = 31342
- 71 + 31271 = 31342
- 83 + 31259 = 31342
- 89 + 31253 = 31342
- 149 + 31193 = 31342
- 191 + 31151 = 31342
- 251 + 31091 = 31342
Showing the first eight; more decompositions exist.
