Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 543018, here are decompositions:

19 + 542999 = 543018
31 + 542987 = 543018
37 + 542981 = 543018
67 + 542951 = 543018
71 + 542947 = 543018
79 + 542939 = 543018
97 + 542921 = 543018
107 + 542911 = 543018

Showing the first eight; more decompositions exist.
