Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542940, here are decompositions:

7 + 542933 = 542940
17 + 542923 = 542940
19 + 542921 = 542940
29 + 542911 = 542940
67 + 542873 = 542940
103 + 542837 = 542940
109 + 542831 = 542940
149 + 542791 = 542940

Showing the first eight; more decompositions exist.
