Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78828, here are decompositions:
- 5 + 78823 = 78828
- 19 + 78809 = 78828
- 31 + 78797 = 78828
- 37 + 78791 = 78828
- 41 + 78787 = 78828
- 47 + 78781 = 78828
- 107 + 78721 = 78828
- 131 + 78697 = 78828
Showing the first eight; more decompositions exist.
