Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21602, here are decompositions:

3 + 21599 = 21602
13 + 21589 = 21602
43 + 21559 = 21602
73 + 21529 = 21602
79 + 21523 = 21602
103 + 21499 = 21602
109 + 21493 = 21602
211 + 21391 = 21602

Showing the first eight; more decompositions exist.
