Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19528, here are decompositions:

59 + 19469 = 19528
71 + 19457 = 19528
101 + 19427 = 19528
107 + 19421 = 19528
137 + 19391 = 19528
149 + 19379 = 19528
227 + 19301 = 19528
239 + 19289 = 19528

Showing the first eight; more decompositions exist.
