Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78814, here are decompositions:
- 5 + 78809 = 78814
- 11 + 78803 = 78814
- 17 + 78797 = 78814
- 23 + 78791 = 78814
- 101 + 78713 = 78814
- 107 + 78707 = 78814
- 191 + 78623 = 78814
- 317 + 78497 = 78814
Showing the first eight; more decompositions exist.
