Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56420, here are decompositions:

3 + 56417 = 56420
19 + 56401 = 56420
37 + 56383 = 56420
43 + 56377 = 56420
61 + 56359 = 56420
109 + 56311 = 56420
151 + 56269 = 56420
157 + 56263 = 56420

Showing the first eight; more decompositions exist.
