Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512690, here are decompositions:

7 + 512683 = 512690
19 + 512671 = 512690
97 + 512593 = 512690
109 + 512581 = 512690
193 + 512497 = 512690
223 + 512467 = 512690
271 + 512419 = 512690
337 + 512353 = 512690

Showing the first eight; more decompositions exist.
