Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548440, here are decompositions:

17 + 548423 = 548440
23 + 548417 = 548440
41 + 548399 = 548440
47 + 548393 = 548440
89 + 548351 = 548440
131 + 548309 = 548440
149 + 548291 = 548440
197 + 548243 = 548440

Showing the first eight; more decompositions exist.
