Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10530, here are decompositions:

17 + 10513 = 10530
29 + 10501 = 10530
31 + 10499 = 10530
43 + 10487 = 10530
53 + 10477 = 10530
67 + 10463 = 10530
71 + 10459 = 10530
73 + 10457 = 10530

Showing the first eight; more decompositions exist.
