Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71320, here are decompositions:
- 3 + 71317 = 71320
- 59 + 71261 = 71320
- 71 + 71249 = 71320
- 83 + 71237 = 71320
- 149 + 71171 = 71320
- 167 + 71153 = 71320
- 173 + 71147 = 71320
- 191 + 71129 = 71320
Showing the first eight; more decompositions exist.
