Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4530, here are decompositions:

7 + 4523 = 4530
11 + 4519 = 4530
13 + 4517 = 4530
17 + 4513 = 4530
23 + 4507 = 4530
37 + 4493 = 4530
47 + 4483 = 4530
67 + 4463 = 4530

Showing the first eight; more decompositions exist.
