Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548878, here are decompositions:

17 + 548861 = 548878
41 + 548837 = 548878
47 + 548831 = 548878
107 + 548771 = 548878
191 + 548687 = 548878
311 + 548567 = 548878
359 + 548519 = 548878
389 + 548489 = 548878

Showing the first eight; more decompositions exist.
