Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23878, here are decompositions:
- 5 + 23873 = 23878
- 47 + 23831 = 23878
- 59 + 23819 = 23878
- 89 + 23789 = 23878
- 131 + 23747 = 23878
- 137 + 23741 = 23878
- 191 + 23687 = 23878
- 251 + 23627 = 23878
Showing the first eight; more decompositions exist.
