Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47420, here are decompositions:

3 + 47417 = 47420
13 + 47407 = 47420
31 + 47389 = 47420
67 + 47353 = 47420
103 + 47317 = 47420
127 + 47293 = 47420
151 + 47269 = 47420
199 + 47221 = 47420

Showing the first eight; more decompositions exist.
