Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66570, here are decompositions:
- 17 + 66553 = 66570
- 29 + 66541 = 66570
- 37 + 66533 = 66570
- 41 + 66529 = 66570
- 47 + 66523 = 66570
- 61 + 66509 = 66570
- 71 + 66499 = 66570
- 79 + 66491 = 66570
Showing the first eight; more decompositions exist.
