Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78268, here are decompositions:
- 89 + 78179 = 78268
- 101 + 78167 = 78268
- 131 + 78137 = 78268
- 167 + 78101 = 78268
- 227 + 78041 = 78268
- 251 + 78017 = 78268
- 269 + 77999 = 78268
- 317 + 77951 = 78268
Showing the first eight; more decompositions exist.
