Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71248, here are decompositions:
- 11 + 71237 = 71248
- 101 + 71147 = 71248
- 167 + 71081 = 71248
- 179 + 71069 = 71248
- 251 + 70997 = 71248
- 257 + 70991 = 71248
- 269 + 70979 = 71248
- 311 + 70937 = 71248
Showing the first eight; more decompositions exist.
