Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 579640, here are decompositions:

3 + 579637 = 579640
11 + 579629 = 579640
29 + 579611 = 579640
53 + 579587 = 579640
71 + 579569 = 579640
101 + 579539 = 579640
107 + 579533 = 579640
137 + 579503 = 579640

Showing the first eight; more decompositions exist.
