Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81024, here are decompositions:
- 5 + 81019 = 81024
- 7 + 81017 = 81024
- 11 + 81013 = 81024
- 23 + 81001 = 81024
- 61 + 80963 = 81024
- 71 + 80953 = 81024
- 101 + 80923 = 81024
- 107 + 80917 = 81024
Showing the first eight; more decompositions exist.
