Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3576, here are decompositions:

5 + 3571 = 3576
17 + 3559 = 3576
19 + 3557 = 3576
29 + 3547 = 3576
37 + 3539 = 3576
43 + 3533 = 3576
47 + 3529 = 3576
59 + 3517 = 3576

Showing the first eight; more decompositions exist.
