Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8586, here are decompositions:

5 + 8581 = 8586
13 + 8573 = 8586
23 + 8563 = 8586
43 + 8543 = 8586
47 + 8539 = 8586
59 + 8527 = 8586
73 + 8513 = 8586
139 + 8447 = 8586

Showing the first eight; more decompositions exist.
