Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66612, here are decompositions:
- 11 + 66601 = 66612
- 19 + 66593 = 66612
- 41 + 66571 = 66612
- 43 + 66569 = 66612
- 59 + 66553 = 66612
- 71 + 66541 = 66612
- 79 + 66533 = 66612
- 83 + 66529 = 66612
Showing the first eight; more decompositions exist.
