Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 585640, here are decompositions:

47 + 585593 = 585640
53 + 585587 = 585640
59 + 585581 = 585640
71 + 585569 = 585640
89 + 585551 = 585640
137 + 585503 = 585640
173 + 585467 = 585640
179 + 585461 = 585640

Showing the first eight; more decompositions exist.
