Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21614, here are decompositions:
- 3 + 21611 = 21614
- 13 + 21601 = 21614
- 37 + 21577 = 21614
- 97 + 21517 = 21614
- 127 + 21487 = 21614
- 181 + 21433 = 21614
- 223 + 21391 = 21614
- 331 + 21283 = 21614
Showing the first eight; more decompositions exist.
