Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87528, here are decompositions:

5 + 87523 = 87528
11 + 87517 = 87528
17 + 87511 = 87528
19 + 87509 = 87528
37 + 87491 = 87528
47 + 87481 = 87528
101 + 87427 = 87528
107 + 87421 = 87528

Showing the first eight; more decompositions exist.
