Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8478, here are decompositions:
- 11 + 8467 = 8478
- 17 + 8461 = 8478
- 31 + 8447 = 8478
- 47 + 8431 = 8478
- 59 + 8419 = 8478
- 89 + 8389 = 8478
- 101 + 8377 = 8478
- 109 + 8369 = 8478
Showing the first eight; more decompositions exist.
