Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5420, here are decompositions:

3 + 5417 = 5420
7 + 5413 = 5420
13 + 5407 = 5420
73 + 5347 = 5420
97 + 5323 = 5420
139 + 5281 = 5420
193 + 5227 = 5420
211 + 5209 = 5420

Showing the first eight; more decompositions exist.
