Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8580, here are decompositions:

7 + 8573 = 8580
17 + 8563 = 8580
37 + 8543 = 8580
41 + 8539 = 8580
43 + 8537 = 8580
53 + 8527 = 8580
59 + 8521 = 8580
67 + 8513 = 8580

Showing the first eight; more decompositions exist.
