Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548438, here are decompositions:

31 + 548407 = 548438
67 + 548371 = 548438
199 + 548239 = 548438
211 + 548227 = 548438
349 + 548089 = 548438
379 + 548059 = 548438
439 + 547999 = 548438
487 + 547951 = 548438

Showing the first eight; more decompositions exist.
