Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3530, here are decompositions:

3 + 3527 = 3530
13 + 3517 = 3530
19 + 3511 = 3530
31 + 3499 = 3530
61 + 3469 = 3530
67 + 3463 = 3530
73 + 3457 = 3530
97 + 3433 = 3530

Showing the first eight; more decompositions exist.
