Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47666, here are decompositions:
- 7 + 47659 = 47666
- 13 + 47653 = 47666
- 37 + 47629 = 47666
- 43 + 47623 = 47666
- 67 + 47599 = 47666
- 97 + 47569 = 47666
- 103 + 47563 = 47666
- 139 + 47527 = 47666
Showing the first eight; more decompositions exist.
