Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556590, here are decompositions:

7 + 556583 = 556590
11 + 556579 = 556590
17 + 556573 = 556590
31 + 556559 = 556590
53 + 556537 = 556590
71 + 556519 = 556590
103 + 556487 = 556590
107 + 556483 = 556590

Showing the first eight; more decompositions exist.
