Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78816, here are decompositions:
- 7 + 78809 = 78816
- 13 + 78803 = 78816
- 19 + 78797 = 78816
- 29 + 78787 = 78816
- 37 + 78779 = 78816
- 79 + 78737 = 78816
- 103 + 78713 = 78816
- 109 + 78707 = 78816
Showing the first eight; more decompositions exist.
