Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21592, here are decompositions:
- 3 + 21589 = 21592
- 5 + 21587 = 21592
- 23 + 21569 = 21592
- 29 + 21563 = 21592
- 71 + 21521 = 21592
- 89 + 21503 = 21592
- 101 + 21491 = 21592
- 173 + 21419 = 21592
Showing the first eight; more decompositions exist.
