Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542928, here are decompositions:

5 + 542923 = 542928
7 + 542921 = 542928
17 + 542911 = 542928
37 + 542891 = 542928
97 + 542831 = 542928
107 + 542821 = 542928
131 + 542797 = 542928
137 + 542791 = 542928

Showing the first eight; more decompositions exist.
