Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20848, here are decompositions:
- 41 + 20807 = 20848
- 59 + 20789 = 20848
- 89 + 20759 = 20848
- 101 + 20747 = 20848
- 131 + 20717 = 20848
- 167 + 20681 = 20848
- 449 + 20399 = 20848
- 479 + 20369 = 20848
Showing the first eight; more decompositions exist.
