Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548278, here are decompositions:

89 + 548189 = 548278
179 + 548099 = 548278
239 + 548039 = 548278
389 + 547889 = 548278
461 + 547817 = 548278
491 + 547787 = 548278
509 + 547769 = 548278
569 + 547709 = 548278

Showing the first eight; more decompositions exist.
