Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66784, here are decompositions:
- 71 + 66713 = 66784
- 83 + 66701 = 66784
- 101 + 66683 = 66784
- 131 + 66653 = 66784
- 167 + 66617 = 66784
- 191 + 66593 = 66784
- 197 + 66587 = 66784
- 251 + 66533 = 66784
Showing the first eight; more decompositions exist.
