Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548782, here are decompositions:

11 + 548771 = 548782
29 + 548753 = 548782
89 + 548693 = 548782
191 + 548591 = 548782
239 + 548543 = 548782
263 + 548519 = 548782
281 + 548501 = 548782
293 + 548489 = 548782

Showing the first eight; more decompositions exist.
