Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21414, here are decompositions:

7 + 21407 = 21414
13 + 21401 = 21414
17 + 21397 = 21414
23 + 21391 = 21414
31 + 21383 = 21414
37 + 21377 = 21414
67 + 21347 = 21414
73 + 21341 = 21414

Showing the first eight; more decompositions exist.
