Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69678, here are decompositions:
- 17 + 69661 = 69678
- 139 + 69539 = 69678
- 179 + 69499 = 69678
- 181 + 69497 = 69678
- 197 + 69481 = 69678
- 211 + 69467 = 69678
- 239 + 69439 = 69678
- 251 + 69427 = 69678
Showing the first eight; more decompositions exist.
