Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68838, here are decompositions:
- 17 + 68821 = 68838
- 19 + 68819 = 68838
- 47 + 68791 = 68838
- 61 + 68777 = 68838
- 67 + 68771 = 68838
- 71 + 68767 = 68838
- 89 + 68749 = 68838
- 101 + 68737 = 68838
Showing the first eight; more decompositions exist.
