Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548402, here are decompositions:

3 + 548399 = 548402
31 + 548371 = 548402
79 + 548323 = 548402
139 + 548263 = 548402
163 + 548239 = 548402
181 + 548221 = 548402
313 + 548089 = 548402
571 + 547831 = 548402

Showing the first eight; more decompositions exist.
