Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15444, here are decompositions:

5 + 15439 = 15444
17 + 15427 = 15444
31 + 15413 = 15444
43 + 15401 = 15444
53 + 15391 = 15444
61 + 15383 = 15444
67 + 15377 = 15444
71 + 15373 = 15444

Showing the first eight; more decompositions exist.
