Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545940, here are decompositions:

7 + 545933 = 545940
11 + 545929 = 545940
23 + 545917 = 545940
29 + 545911 = 545940
41 + 545899 = 545940
47 + 545893 = 545940
67 + 545873 = 545940
97 + 545843 = 545940

Showing the first eight; more decompositions exist.
