Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47580, here are decompositions:

11 + 47569 = 47580
17 + 47563 = 47580
37 + 47543 = 47580
47 + 47533 = 47580
53 + 47527 = 47580
59 + 47521 = 47580
67 + 47513 = 47580
73 + 47507 = 47580

Showing the first eight; more decompositions exist.
