Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66572, here are decompositions:
- 3 + 66569 = 66572
- 19 + 66553 = 66572
- 31 + 66541 = 66572
- 43 + 66529 = 66572
- 73 + 66499 = 66572
- 109 + 66463 = 66572
- 199 + 66373 = 66572
- 211 + 66361 = 66572
Showing the first eight; more decompositions exist.
