Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512660, here are decompositions:

3 + 512657 = 512660
19 + 512641 = 512660
67 + 512593 = 512660
79 + 512581 = 512660
139 + 512521 = 512660
157 + 512503 = 512660
163 + 512497 = 512660
193 + 512467 = 512660

Showing the first eight; more decompositions exist.
