Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84520, here are decompositions:
- 11 + 84509 = 84520
- 17 + 84503 = 84520
- 53 + 84467 = 84520
- 71 + 84449 = 84520
- 83 + 84437 = 84520
- 89 + 84431 = 84520
- 113 + 84407 = 84520
- 131 + 84389 = 84520
Showing the first eight; more decompositions exist.
