Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66912, here are decompositions:
- 23 + 66889 = 66912
- 29 + 66883 = 66912
- 59 + 66853 = 66912
- 61 + 66851 = 66912
- 71 + 66841 = 66912
- 103 + 66809 = 66912
- 149 + 66763 = 66912
- 163 + 66749 = 66912
Showing the first eight; more decompositions exist.
