Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21594, here are decompositions:

5 + 21589 = 21594
7 + 21587 = 21594
17 + 21577 = 21594
31 + 21563 = 21594
37 + 21557 = 21594
71 + 21523 = 21594
73 + 21521 = 21594
101 + 21493 = 21594

Showing the first eight; more decompositions exist.
