Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28492, here are decompositions:
- 29 + 28463 = 28492
- 53 + 28439 = 28492
- 59 + 28433 = 28492
- 83 + 28409 = 28492
- 89 + 28403 = 28492
- 173 + 28319 = 28492
- 263 + 28229 = 28492
- 281 + 28211 = 28492
Showing the first eight; more decompositions exist.
