Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548728, here are decompositions:

41 + 548687 = 548728
71 + 548657 = 548728
137 + 548591 = 548728
149 + 548579 = 548728
227 + 548501 = 548728
239 + 548489 = 548728
269 + 548459 = 548728
311 + 548417 = 548728

Showing the first eight; more decompositions exist.
