Goldbach decomposition

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.
