Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61824, here are decompositions:
- 5 + 61819 = 61824
- 11 + 61813 = 61824
- 43 + 61781 = 61824
- 67 + 61757 = 61824
- 73 + 61751 = 61824
- 101 + 61723 = 61824
- 107 + 61717 = 61824
- 137 + 61687 = 61824
Showing the first eight; more decompositions exist.
