Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 585520, here are decompositions:

3 + 585517 = 585520
17 + 585503 = 585520
53 + 585467 = 585520
59 + 585461 = 585520
83 + 585437 = 585520
107 + 585413 = 585520
137 + 585383 = 585520
179 + 585341 = 585520

Showing the first eight; more decompositions exist.
