Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66730, here are decompositions:
- 17 + 66713 = 66730
- 29 + 66701 = 66730
- 47 + 66683 = 66730
- 101 + 66629 = 66730
- 113 + 66617 = 66730
- 137 + 66593 = 66730
- 197 + 66533 = 66730
- 239 + 66491 = 66730
Showing the first eight; more decompositions exist.
