Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542884, here are decompositions:

11 + 542873 = 542884
47 + 542837 = 542884
53 + 542831 = 542884
101 + 542783 = 542884
113 + 542771 = 542884
137 + 542747 = 542884
191 + 542693 = 542884
197 + 542687 = 542884

Showing the first eight; more decompositions exist.
