Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67860, here are decompositions:
- 7 + 67853 = 67860
- 17 + 67843 = 67860
- 31 + 67829 = 67860
- 41 + 67819 = 67860
- 53 + 67807 = 67860
- 59 + 67801 = 67860
- 71 + 67789 = 67860
- 83 + 67777 = 67860
Showing the first eight; more decompositions exist.
