Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 558540, here are decompositions:

7 + 558533 = 558540
11 + 558529 = 558540
19 + 558521 = 558540
41 + 558499 = 558540
43 + 558497 = 558540
61 + 558479 = 558540
67 + 558473 = 558540
71 + 558469 = 558540

Showing the first eight; more decompositions exist.
