Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511586, here are decompositions:

3 + 511583 = 511586
7 + 511579 = 511586
13 + 511573 = 511586
37 + 511549 = 511586
67 + 511519 = 511586
79 + 511507 = 511586
109 + 511477 = 511586
139 + 511447 = 511586

Showing the first eight; more decompositions exist.
