Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548388, here are decompositions:

17 + 548371 = 548388
37 + 548351 = 548388
41 + 548347 = 548388
79 + 548309 = 548388
97 + 548291 = 548388
149 + 548239 = 548388
167 + 548221 = 548388
199 + 548189 = 548388

Showing the first eight; more decompositions exist.
