Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18528, here are decompositions:

5 + 18523 = 18528
7 + 18521 = 18528
11 + 18517 = 18528
47 + 18481 = 18528
67 + 18461 = 18528
71 + 18457 = 18528
89 + 18439 = 18528
101 + 18427 = 18528

Showing the first eight; more decompositions exist.
