Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66474, here are decompositions:

7 + 66467 = 66474
11 + 66463 = 66474
17 + 66457 = 66474
43 + 66431 = 66474
61 + 66413 = 66474
71 + 66403 = 66474
97 + 66377 = 66474
101 + 66373 = 66474

Showing the first eight; more decompositions exist.
