Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548378, here are decompositions:

7 + 548371 = 548378
31 + 548347 = 548378
139 + 548239 = 548378
151 + 548227 = 548378
157 + 548221 = 548378
379 + 547999 = 548378
421 + 547957 = 548378
547 + 547831 = 548378

Showing the first eight; more decompositions exist.
