Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15432, here are decompositions:

5 + 15427 = 15432
19 + 15413 = 15432
31 + 15401 = 15432
41 + 15391 = 15432
59 + 15373 = 15432
71 + 15361 = 15432
73 + 15359 = 15432
83 + 15349 = 15432

Showing the first eight; more decompositions exist.
