Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3558, here are decompositions:

11 + 3547 = 3558
17 + 3541 = 3558
19 + 3539 = 3558
29 + 3529 = 3558
31 + 3527 = 3558
41 + 3517 = 3558
47 + 3511 = 3558
59 + 3499 = 3558

Showing the first eight; more decompositions exist.
