Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21714, here are decompositions:
- 13 + 21701 = 21714
- 31 + 21683 = 21714
- 41 + 21673 = 21714
- 53 + 21661 = 21714
- 67 + 21647 = 21714
- 97 + 21617 = 21714
- 101 + 21613 = 21714
- 103 + 21611 = 21714
Showing the first eight; more decompositions exist.
