Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66504, here are decompositions:
- 5 + 66499 = 66504
- 13 + 66491 = 66504
- 37 + 66467 = 66504
- 41 + 66463 = 66504
- 47 + 66457 = 66504
- 73 + 66431 = 66504
- 101 + 66403 = 66504
- 127 + 66377 = 66504
Showing the first eight; more decompositions exist.
