Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66604, here are decompositions:
- 3 + 66601 = 66604
- 11 + 66593 = 66604
- 17 + 66587 = 66604
- 71 + 66533 = 66604
- 113 + 66491 = 66604
- 137 + 66467 = 66604
- 173 + 66431 = 66604
- 191 + 66413 = 66604
Showing the first eight; more decompositions exist.
