Goldbach decomposition

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.
