Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511562, here are decompositions:

3 + 511559 = 511562
13 + 511549 = 511562
43 + 511519 = 511562
109 + 511453 = 511562
211 + 511351 = 511562
229 + 511333 = 511562
283 + 511279 = 511562
349 + 511213 = 511562

Showing the first eight; more decompositions exist.
