Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553530, here are decompositions:

13 + 553517 = 553530
17 + 553513 = 553530
23 + 553507 = 553530
59 + 553471 = 553530
67 + 553463 = 553530
73 + 553457 = 553530
83 + 553447 = 553530
97 + 553433 = 553530

Showing the first eight; more decompositions exist.
