Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3540, here are decompositions:

7 + 3533 = 3540
11 + 3529 = 3540
13 + 3527 = 3540
23 + 3517 = 3540
29 + 3511 = 3540
41 + 3499 = 3540
71 + 3469 = 3540
73 + 3467 = 3540

Showing the first eight; more decompositions exist.
