Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71298, here are decompositions:
- 5 + 71293 = 71298
- 11 + 71287 = 71298
- 37 + 71261 = 71298
- 41 + 71257 = 71298
- 61 + 71237 = 71298
- 89 + 71209 = 71298
- 107 + 71191 = 71298
- 127 + 71171 = 71298
Showing the first eight; more decompositions exist.
