Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548838, here are decompositions:

5 + 548833 = 548838
7 + 548831 = 548838
11 + 548827 = 548838
47 + 548791 = 548838
67 + 548771 = 548838
89 + 548749 = 548838
131 + 548707 = 548838
151 + 548687 = 548838

Showing the first eight; more decompositions exist.
