Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21734, here are decompositions:
- 7 + 21727 = 21734
- 61 + 21673 = 21734
- 73 + 21661 = 21734
- 157 + 21577 = 21734
- 211 + 21523 = 21734
- 241 + 21493 = 21734
- 337 + 21397 = 21734
- 421 + 21313 = 21734
Showing the first eight; more decompositions exist.
