Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548842, here are decompositions:

5 + 548837 = 548842
11 + 548831 = 548842
59 + 548783 = 548842
71 + 548771 = 548842
89 + 548753 = 548842
149 + 548693 = 548842
251 + 548591 = 548842
263 + 548579 = 548842

Showing the first eight; more decompositions exist.
