Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3582, here are decompositions:

11 + 3571 = 3582
23 + 3559 = 3582
41 + 3541 = 3582
43 + 3539 = 3582
53 + 3529 = 3582
71 + 3511 = 3582
83 + 3499 = 3582
113 + 3469 = 3582

Showing the first eight; more decompositions exist.
