Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553518, here are decompositions:

5 + 553513 = 553518
11 + 553507 = 553518
37 + 553481 = 553518
47 + 553471 = 553518
61 + 553457 = 553518
71 + 553447 = 553518
79 + 553439 = 553518
101 + 553417 = 553518

Showing the first eight; more decompositions exist.
