Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13528, here are decompositions:

5 + 13523 = 13528
29 + 13499 = 13528
41 + 13487 = 13528
59 + 13469 = 13528
71 + 13457 = 13528
107 + 13421 = 13528
131 + 13397 = 13528
191 + 13337 = 13528

Showing the first eight; more decompositions exist.
