Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21474, here are decompositions:

7 + 21467 = 21474
41 + 21433 = 21474
67 + 21407 = 21474
73 + 21401 = 21474
83 + 21391 = 21474
97 + 21377 = 21474
127 + 21347 = 21474
151 + 21323 = 21474

Showing the first eight; more decompositions exist.
