Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80808, here are decompositions:
- 5 + 80803 = 80808
- 19 + 80789 = 80808
- 29 + 80779 = 80808
- 31 + 80777 = 80808
- 47 + 80761 = 80808
- 59 + 80749 = 80808
- 61 + 80747 = 80808
- 71 + 80737 = 80808
Showing the first eight; more decompositions exist.
