Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545100, here are decompositions:

7 + 545093 = 545100
11 + 545089 = 545100
13 + 545087 = 545100
37 + 545063 = 545100
43 + 545057 = 545100
67 + 545033 = 545100
71 + 545029 = 545100
137 + 544963 = 545100

Showing the first eight; more decompositions exist.
