Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78928, here are decompositions:
- 41 + 78887 = 78928
- 71 + 78857 = 78928
- 89 + 78839 = 78928
- 131 + 78797 = 78928
- 137 + 78791 = 78928
- 149 + 78779 = 78928
- 191 + 78737 = 78928
- 359 + 78569 = 78928
Showing the first eight; more decompositions exist.
