Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80784, here are decompositions:
- 5 + 80779 = 80784
- 7 + 80777 = 80784
- 23 + 80761 = 80784
- 37 + 80747 = 80784
- 47 + 80737 = 80784
- 71 + 80713 = 80784
- 83 + 80701 = 80784
- 97 + 80687 = 80784
Showing the first eight; more decompositions exist.
