Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66574, here are decompositions:
- 3 + 66571 = 66574
- 5 + 66569 = 66574
- 41 + 66533 = 66574
- 83 + 66491 = 66574
- 107 + 66467 = 66574
- 191 + 66383 = 66574
- 197 + 66377 = 66574
- 227 + 66347 = 66574
Showing the first eight; more decompositions exist.
