Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512678, here are decompositions:

7 + 512671 = 512678
37 + 512641 = 512678
97 + 512581 = 512678
109 + 512569 = 512678
157 + 512521 = 512678
181 + 512497 = 512678
211 + 512467 = 512678
367 + 512311 = 512678

Showing the first eight; more decompositions exist.
