Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84490, here are decompositions:
- 23 + 84467 = 84490
- 41 + 84449 = 84490
- 47 + 84443 = 84490
- 53 + 84437 = 84490
- 59 + 84431 = 84490
- 83 + 84407 = 84490
- 89 + 84401 = 84490
- 101 + 84389 = 84490
Showing the first eight; more decompositions exist.
