Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80982, here are decompositions:
- 19 + 80963 = 80982
- 29 + 80953 = 80982
- 53 + 80929 = 80982
- 59 + 80923 = 80982
- 71 + 80911 = 80982
- 73 + 80909 = 80982
- 149 + 80833 = 80982
- 151 + 80831 = 80982
Showing the first eight; more decompositions exist.
