Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23580, here are decompositions:

13 + 23567 = 23580
17 + 23563 = 23580
19 + 23561 = 23580
23 + 23557 = 23580
31 + 23549 = 23580
41 + 23539 = 23580
43 + 23537 = 23580
71 + 23509 = 23580

Showing the first eight; more decompositions exist.
