Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16420, here are decompositions:

3 + 16417 = 16420
59 + 16361 = 16420
71 + 16349 = 16420
101 + 16319 = 16420
167 + 16253 = 16420
191 + 16229 = 16420
197 + 16223 = 16420
227 + 16193 = 16420

Showing the first eight; more decompositions exist.
