Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71256, here are decompositions:
- 7 + 71249 = 71256
- 19 + 71237 = 71256
- 23 + 71233 = 71256
- 47 + 71209 = 71256
- 89 + 71167 = 71256
- 103 + 71153 = 71256
- 109 + 71147 = 71256
- 113 + 71143 = 71256
Showing the first eight; more decompositions exist.
