Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548558, here are decompositions:

37 + 548521 = 548558
97 + 548461 = 548558
151 + 548407 = 548558
211 + 548347 = 548558
331 + 548227 = 548558
337 + 548221 = 548558
499 + 548059 = 548558
601 + 547957 = 548558

Showing the first eight; more decompositions exist.
