Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84540, here are decompositions:
- 7 + 84533 = 84540
- 17 + 84523 = 84540
- 19 + 84521 = 84540
- 31 + 84509 = 84540
- 37 + 84503 = 84540
- 41 + 84499 = 84540
- 59 + 84481 = 84540
- 73 + 84467 = 84540
Showing the first eight; more decompositions exist.
