Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21732, here are decompositions:

5 + 21727 = 21732
19 + 21713 = 21732
31 + 21701 = 21732
59 + 21673 = 21732
71 + 21661 = 21732
83 + 21649 = 21732
131 + 21601 = 21732
163 + 21569 = 21732

Showing the first eight; more decompositions exist.
