Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68158, here are decompositions:
- 11 + 68147 = 68158
- 17 + 68141 = 68158
- 47 + 68111 = 68158
- 59 + 68099 = 68158
- 71 + 68087 = 68158
- 179 + 67979 = 68158
- 191 + 67967 = 68158
- 197 + 67961 = 68158
Showing the first eight; more decompositions exist.
