Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512028, here are decompositions:

7 + 512021 = 512028
17 + 512011 = 512028
19 + 512009 = 512028
31 + 511997 = 512028
37 + 511991 = 512028
67 + 511961 = 512028
89 + 511939 = 512028
131 + 511897 = 512028

Showing the first eight; more decompositions exist.
