Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68780, here are decompositions:
- 3 + 68777 = 68780
- 13 + 68767 = 68780
- 31 + 68749 = 68780
- 37 + 68743 = 68780
- 43 + 68737 = 68780
- 67 + 68713 = 68780
- 97 + 68683 = 68780
- 199 + 68581 = 68780
Showing the first eight; more decompositions exist.
