Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77864, here are decompositions:
- 67 + 77797 = 77864
- 103 + 77761 = 77864
- 151 + 77713 = 77864
- 223 + 77641 = 77864
- 277 + 77587 = 77864
- 307 + 77557 = 77864
- 313 + 77551 = 77864
- 337 + 77527 = 77864
Showing the first eight; more decompositions exist.
