Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78658, here are decompositions:
- 5 + 78653 = 78658
- 89 + 78569 = 78658
- 149 + 78509 = 78658
- 179 + 78479 = 78658
- 191 + 78467 = 78658
- 257 + 78401 = 78658
- 311 + 78347 = 78658
- 317 + 78341 = 78658
Showing the first eight; more decompositions exist.
