Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67872, here are decompositions:
- 5 + 67867 = 67872
- 19 + 67853 = 67872
- 29 + 67843 = 67872
- 43 + 67829 = 67872
- 53 + 67819 = 67872
- 71 + 67801 = 67872
- 83 + 67789 = 67872
- 89 + 67783 = 67872
Showing the first eight; more decompositions exist.
