Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71250, here are decompositions:
- 13 + 71237 = 71250
- 17 + 71233 = 71250
- 41 + 71209 = 71250
- 59 + 71191 = 71250
- 79 + 71171 = 71250
- 83 + 71167 = 71250
- 89 + 71161 = 71250
- 97 + 71153 = 71250
Showing the first eight; more decompositions exist.
