Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3572, here are decompositions:

13 + 3559 = 3572
31 + 3541 = 3572
43 + 3529 = 3572
61 + 3511 = 3572
73 + 3499 = 3572
103 + 3469 = 3572
109 + 3463 = 3572
139 + 3433 = 3572

Showing the first eight; more decompositions exist.
