Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511582, here are decompositions:

3 + 511579 = 511582
23 + 511559 = 511582
41 + 511541 = 511582
59 + 511523 = 511582
173 + 511409 = 511582
191 + 511391 = 511582
293 + 511289 = 511582
359 + 511223 = 511582

Showing the first eight; more decompositions exist.
