Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548450, here are decompositions:

43 + 548407 = 548450
79 + 548371 = 548450
103 + 548347 = 548450
127 + 548323 = 548450
211 + 548239 = 548450
223 + 548227 = 548450
229 + 548221 = 548450
307 + 548143 = 548450

Showing the first eight; more decompositions exist.
