Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542944, here are decompositions:

5 + 542939 = 542944
11 + 542933 = 542944
23 + 542921 = 542944
53 + 542891 = 542944
71 + 542873 = 542944
107 + 542837 = 542944
113 + 542831 = 542944
173 + 542771 = 542944

Showing the first eight; more decompositions exist.
