Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512920, here are decompositions:

3 + 512917 = 512920
17 + 512903 = 512920
29 + 512891 = 512920
71 + 512849 = 512920
101 + 512819 = 512920
173 + 512747 = 512920
179 + 512741 = 512920
257 + 512663 = 512920

Showing the first eight; more decompositions exist.
