Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15620, here are decompositions:

13 + 15607 = 15620
19 + 15601 = 15620
37 + 15583 = 15620
61 + 15559 = 15620
79 + 15541 = 15620
109 + 15511 = 15620
127 + 15493 = 15620
181 + 15439 = 15620

Showing the first eight; more decompositions exist.
