Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548740, here are decompositions:

47 + 548693 = 548740
53 + 548687 = 548740
83 + 548657 = 548740
149 + 548591 = 548740
173 + 548567 = 548740
197 + 548543 = 548740
239 + 548501 = 548740
251 + 548489 = 548740

Showing the first eight; more decompositions exist.
