Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66636, here are decompositions:
- 7 + 66629 = 66636
- 19 + 66617 = 66636
- 43 + 66593 = 66636
- 67 + 66569 = 66636
- 83 + 66553 = 66636
- 103 + 66533 = 66636
- 107 + 66529 = 66636
- 113 + 66523 = 66636
Showing the first eight; more decompositions exist.
