Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511572, here are decompositions:

13 + 511559 = 511572
23 + 511549 = 511572
31 + 511541 = 511572
53 + 511519 = 511572
109 + 511463 = 511572
163 + 511409 = 511572
181 + 511391 = 511572
211 + 511361 = 511572

Showing the first eight; more decompositions exist.
