Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66528, here are decompositions:
- 5 + 66523 = 66528
- 19 + 66509 = 66528
- 29 + 66499 = 66528
- 37 + 66491 = 66528
- 61 + 66467 = 66528
- 71 + 66457 = 66528
- 79 + 66449 = 66528
- 97 + 66431 = 66528
Showing the first eight; more decompositions exist.
