Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21434, here are decompositions:

37 + 21397 = 21434
43 + 21391 = 21434
151 + 21283 = 21434
157 + 21277 = 21434
223 + 21211 = 21434
241 + 21193 = 21434
271 + 21163 = 21434
277 + 21157 = 21434

Showing the first eight; more decompositions exist.
