Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102528, here are decompositions:

5 + 102523 = 102528
29 + 102499 = 102528
31 + 102497 = 102528
47 + 102481 = 102528
67 + 102461 = 102528
131 + 102397 = 102528
191 + 102337 = 102528
199 + 102329 = 102528

Showing the first eight; more decompositions exist.
