Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68290, here are decompositions:
- 11 + 68279 = 68290
- 29 + 68261 = 68290
- 71 + 68219 = 68290
- 83 + 68207 = 68290
- 149 + 68141 = 68290
- 179 + 68111 = 68290
- 191 + 68099 = 68290
- 311 + 67979 = 68290
Showing the first eight; more decompositions exist.
