Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65580, here are decompositions:

17 + 65563 = 65580
23 + 65557 = 65580
29 + 65551 = 65580
37 + 65543 = 65580
41 + 65539 = 65580
43 + 65537 = 65580
59 + 65521 = 65580
61 + 65519 = 65580

Showing the first eight; more decompositions exist.
