Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28452, here are decompositions:
- 5 + 28447 = 28452
- 13 + 28439 = 28452
- 19 + 28433 = 28452
- 23 + 28429 = 28452
- 41 + 28411 = 28452
- 43 + 28409 = 28452
- 59 + 28393 = 28452
- 101 + 28351 = 28452
Showing the first eight; more decompositions exist.
