Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518026, here are decompositions:

59 + 517967 = 518026
107 + 517919 = 518026
149 + 517877 = 518026
293 + 517733 = 518026
389 + 517637 = 518026
449 + 517577 = 518026
479 + 517547 = 518026
557 + 517469 = 518026

Showing the first eight; more decompositions exist.
