Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545066, here are decompositions:

3 + 545063 = 545066
37 + 545029 = 545066
43 + 545023 = 545066
103 + 544963 = 545066
139 + 544927 = 545066
163 + 544903 = 545066
229 + 544837 = 545066
307 + 544759 = 545066

Showing the first eight; more decompositions exist.
