Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66534, here are decompositions:
- 5 + 66529 = 66534
- 11 + 66523 = 66534
- 43 + 66491 = 66534
- 67 + 66467 = 66534
- 71 + 66463 = 66534
- 103 + 66431 = 66534
- 131 + 66403 = 66534
- 151 + 66383 = 66534
Showing the first eight; more decompositions exist.
