Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28470, here are decompositions:
- 7 + 28463 = 28470
- 23 + 28447 = 28470
- 31 + 28439 = 28470
- 37 + 28433 = 28470
- 41 + 28429 = 28470
- 59 + 28411 = 28470
- 61 + 28409 = 28470
- 67 + 28403 = 28470
Showing the first eight; more decompositions exist.
