Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28522, here are decompositions:
- 5 + 28517 = 28522
- 23 + 28499 = 28522
- 29 + 28493 = 28522
- 59 + 28463 = 28522
- 83 + 28439 = 28522
- 89 + 28433 = 28522
- 113 + 28409 = 28522
- 173 + 28349 = 28522
Showing the first eight; more decompositions exist.
