Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111528, here are decompositions:

7 + 111521 = 111528
19 + 111509 = 111528
31 + 111497 = 111528
37 + 111491 = 111528
41 + 111487 = 111528
61 + 111467 = 111528
89 + 111439 = 111528
97 + 111431 = 111528

Showing the first eight; more decompositions exist.
