Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21348, here are decompositions:

7 + 21341 = 21348
29 + 21319 = 21348
31 + 21317 = 21348
71 + 21277 = 21348
79 + 21269 = 21348
101 + 21247 = 21348
127 + 21221 = 21348
137 + 21211 = 21348

Showing the first eight; more decompositions exist.
