Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3570, here are decompositions:

11 + 3559 = 3570
13 + 3557 = 3570
23 + 3547 = 3570
29 + 3541 = 3570
31 + 3539 = 3570
37 + 3533 = 3570
41 + 3529 = 3570
43 + 3527 = 3570

Showing the first eight; more decompositions exist.
