Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512712, here are decompositions:

29 + 512683 = 512712
41 + 512671 = 512712
71 + 512641 = 512712
103 + 512609 = 512712
131 + 512581 = 512712
139 + 512573 = 512712
181 + 512531 = 512712
191 + 512521 = 512712

Showing the first eight; more decompositions exist.
