Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80000, here are decompositions:
- 3 + 79997 = 80000
- 13 + 79987 = 80000
- 61 + 79939 = 80000
- 97 + 79903 = 80000
- 127 + 79873 = 80000
- 139 + 79861 = 80000
- 157 + 79843 = 80000
- 199 + 79801 = 80000
Showing the first eight; more decompositions exist.
