Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80838, here are decompositions:
- 5 + 80833 = 80838
- 7 + 80831 = 80838
- 19 + 80819 = 80838
- 29 + 80809 = 80838
- 59 + 80779 = 80838
- 61 + 80777 = 80838
- 89 + 80749 = 80838
- 101 + 80737 = 80838
Showing the first eight; more decompositions exist.
