Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122884, here are decompositions:
- 17 + 122867 = 122884
- 23 + 122861 = 122884
- 107 + 122777 = 122884
- 131 + 122753 = 122884
- 191 + 122693 = 122884
- 233 + 122651 = 122884
- 383 + 122501 = 122884
- 431 + 122453 = 122884
Showing the first eight; more decompositions exist.
