Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 582, here are decompositions:

5 + 577 = 582
11 + 571 = 582
13 + 569 = 582
19 + 563 = 582
41 + 541 = 582
59 + 523 = 582
61 + 521 = 582
73 + 509 = 582

Showing the first eight; more decompositions exist.
