Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15514, here are decompositions:

3 + 15511 = 15514
17 + 15497 = 15514
41 + 15473 = 15514
47 + 15467 = 15514
53 + 15461 = 15514
71 + 15443 = 15514
101 + 15413 = 15514
113 + 15401 = 15514

Showing the first eight; more decompositions exist.
