Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78328, here are decompositions:
- 11 + 78317 = 78328
- 17 + 78311 = 78328
- 137 + 78191 = 78328
- 149 + 78179 = 78328
- 191 + 78137 = 78328
- 227 + 78101 = 78328
- 269 + 78059 = 78328
- 311 + 78017 = 78328
Showing the first eight; more decompositions exist.
