Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548420, here are decompositions:

3 + 548417 = 548420
13 + 548407 = 548420
73 + 548347 = 548420
97 + 548323 = 548420
157 + 548263 = 548420
181 + 548239 = 548420
193 + 548227 = 548420
199 + 548221 = 548420

Showing the first eight; more decompositions exist.
