Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548398, here are decompositions:

5 + 548393 = 548398
47 + 548351 = 548398
89 + 548309 = 548398
107 + 548291 = 548398
197 + 548201 = 548398
281 + 548117 = 548398
359 + 548039 = 548398
509 + 547889 = 548398

Showing the first eight; more decompositions exist.
