Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78800, here are decompositions:
- 3 + 78797 = 78800
- 13 + 78787 = 78800
- 19 + 78781 = 78800
- 79 + 78721 = 78800
- 103 + 78697 = 78800
- 109 + 78691 = 78800
- 151 + 78649 = 78800
- 157 + 78643 = 78800
Showing the first eight; more decompositions exist.
