Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545026, here are decompositions:

3 + 545023 = 545026
47 + 544979 = 545026
89 + 544937 = 545026
107 + 544919 = 545026
137 + 544889 = 545026
149 + 544877 = 545026
233 + 544793 = 545026
269 + 544757 = 545026

Showing the first eight; more decompositions exist.
