Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518582, here are decompositions:

3 + 518579 = 518582
61 + 518521 = 518582
73 + 518509 = 518582
109 + 518473 = 518582
151 + 518431 = 518582
193 + 518389 = 518582
241 + 518341 = 518582
271 + 518311 = 518582

Showing the first eight; more decompositions exist.
