Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71386, here are decompositions:
- 23 + 71363 = 71386
- 47 + 71339 = 71386
- 53 + 71333 = 71386
- 59 + 71327 = 71386
- 137 + 71249 = 71386
- 149 + 71237 = 71386
- 233 + 71153 = 71386
- 239 + 71147 = 71386
Showing the first eight; more decompositions exist.
