Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78806, here are decompositions:
- 3 + 78803 = 78806
- 19 + 78787 = 78806
- 109 + 78697 = 78806
- 157 + 78649 = 78806
- 163 + 78643 = 78806
- 199 + 78607 = 78806
- 223 + 78583 = 78806
- 229 + 78577 = 78806
Showing the first eight; more decompositions exist.
