Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32538, here are decompositions:
- 5 + 32533 = 32538
- 7 + 32531 = 32538
- 31 + 32507 = 32538
- 41 + 32497 = 32538
- 47 + 32491 = 32538
- 59 + 32479 = 32538
- 71 + 32467 = 32538
- 97 + 32441 = 32538
Showing the first eight; more decompositions exist.
