Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15570, here are decompositions:

11 + 15559 = 15570
19 + 15551 = 15570
29 + 15541 = 15570
43 + 15527 = 15570
59 + 15511 = 15570
73 + 15497 = 15570
97 + 15473 = 15570
103 + 15467 = 15570

Showing the first eight; more decompositions exist.
