Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71306, here are decompositions:
- 13 + 71293 = 71306
- 19 + 71287 = 71306
- 43 + 71263 = 71306
- 73 + 71233 = 71306
- 97 + 71209 = 71306
- 139 + 71167 = 71306
- 163 + 71143 = 71306
- 283 + 71023 = 71306
Showing the first eight; more decompositions exist.
