Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548428, here are decompositions:

5 + 548423 = 548428
11 + 548417 = 548428
29 + 548399 = 548428
137 + 548291 = 548428
227 + 548201 = 548428
239 + 548189 = 548428
311 + 548117 = 548428
359 + 548069 = 548428

Showing the first eight; more decompositions exist.
