Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78804, here are decompositions:
- 7 + 78797 = 78804
- 13 + 78791 = 78804
- 17 + 78787 = 78804
- 23 + 78781 = 78804
- 67 + 78737 = 78804
- 83 + 78721 = 78804
- 97 + 78707 = 78804
- 107 + 78697 = 78804
Showing the first eight; more decompositions exist.
