Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63420, here are decompositions:

11 + 63409 = 63420
23 + 63397 = 63420
29 + 63391 = 63420
31 + 63389 = 63420
43 + 63377 = 63420
53 + 63367 = 63420
59 + 63361 = 63420
67 + 63353 = 63420

Showing the first eight; more decompositions exist.
