Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542856, here are decompositions:

19 + 542837 = 542856
59 + 542797 = 542856
73 + 542783 = 542856
109 + 542747 = 542856
137 + 542719 = 542856
163 + 542693 = 542856
173 + 542683 = 542856
257 + 542599 = 542856

Showing the first eight; more decompositions exist.
