Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545040, here are decompositions:

7 + 545033 = 545040
11 + 545029 = 545040
17 + 545023 = 545040
61 + 544979 = 545040
79 + 544961 = 545040
103 + 544937 = 545040
113 + 544927 = 545040
137 + 544903 = 545040

Showing the first eight; more decompositions exist.
