Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548018, here are decompositions:

19 + 547999 = 548018
61 + 547957 = 548018
67 + 547951 = 548018
109 + 547909 = 548018
199 + 547819 = 548018
271 + 547747 = 548018
277 + 547741 = 548018
337 + 547681 = 548018

Showing the first eight; more decompositions exist.
