Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5580, here are decompositions:

7 + 5573 = 5580
11 + 5569 = 5580
17 + 5563 = 5580
23 + 5557 = 5580
53 + 5527 = 5580
59 + 5521 = 5580
61 + 5519 = 5580
73 + 5507 = 5580

Showing the first eight; more decompositions exist.
